inkscape has encountered an internal error and will close now

I would try uninstalling Inkscape and re-installing. There were reports of a problem with the .91 uninstaller.

If that doesn't help, please find out if this bug report applies to you: https://bugs.launchpad.net/inkscape/+bug/1495386 (it may be a font that is causing the crash on startup).

You can try to get a more helpful error message on the command line by starting Inkscape from the command line by entering 'inkscape' there.

Thankyou both.
The problem was a Font file, just as you said.
I had to eliminate one Font with special characters in the filename.

Could you maybe attach the conflicting font to the linked bug report (or mail it to me directly if there are licensing considerations?). Also please post the codepage [1] used by your system as well the "system locale" and "input locale" [2]

This is a longstanding bug (and a nasty one at that), but as far as I know none of the developers was able to reproduce it so far, so there is no possibility to fix it...

[1] you can get the active code page by executing the command "chcp" on a console
[2] you can get "system locale" and "input locale" by executing the command "systeminfo" on a console

Hi, I don't know how to attach the fonts files but I already emailed to you.
[1] My codepage is 850.
[2] This is what I get with executing systeminfo command.

Thank you very much!

I'm afraid I'm still not able to reproduce the bug on my system. :-(
Two of the three fonts (the TrueType Fonts, *.ttf) work just fine and I can use them in Inkscape. The third (AESYSMAT.FON) can not be loaded in Inkscape (console output [1]), but nothing crashes.

The last thing I can think off is switching my system locale to Español (México) to match your settings and see if it makes a difference. If that doesn't change anything I'm out of ideas... :-/

[1] Gtk-WARNING **: Failed to set text from markup due to error parsing markup: Error on line 1 char 29: Invalid UTF-8 encoded text in name - not valid '\xc6 Systematic -BRK- '

Note "\xc6" is the UTF8 character code that results when interpreting an ASCII "Æ" without doing proper character conversion.

Yay! Got it to crash! (I'd never thought that could make me happy ;-) )

The problem occurs for me when setting Inkscape locale to Spanish (I did that by using "set LANG=es-MX" on the console before launching Inkscape from that console).
It does not crash on startup but when selecting the "Æ Systematic TT BRKRegular" font in Inkscape (I'm now seeing three fonts, so it's likely the one that could no be used before is now causing the crash).

I'll investigate further and let you know if I can come up with a solution.

Thank you very much!

Eduard just made a code change that prevents Inkscape from crashing. With that fix, the font that would cause the crash is not available for use in Inkscape, but that nasty crash on startup is hopefully fixed.

Great work, Eduard + Elisabet :)

You're noticing everything Maren ;-)
I was still busy with building a testing version of Inkscape 0.92.x (the stable branch) which is available to download from [1] now.

@Elisabeth: If you could download that version and test if it avoids the crash for you that would be extremely helpful!
As I was not able to fully reproduce the issue (Inkscape crashed only on font selection for me - not on startup) there's still a slight chance that you hit yet another issue.

LOL, yes, Eduard :D
I'm subscribed to commits to 0.92.x, and I love reading your detailed commit messages.

(and for spam removal reasons, I'm subscribed to new resources on inkscape.org, just in case you were wondering ;-) )
