TypeError: argument 1 of qRegisterResourceData() has an invalid type

Good day,
First of all, thanks for your time and the answers.

The software that I installed was:
- Bazaar-1.14.1-OSX10.5.dmg
- qt-mac-opensource-4.5.2
- sip-4.8.1
- PyQt-mac-gpl-4.5.2-snapshot-20090627
- python-2.6.2-macosx2009-04-16.dmg (That version of Bazaar uses the 2.5 version of python)

The System that I use is:
- iMac8,1
- Intel Core 2 Duo
- 2.4 GHz

And when I try to execute a "qdiff" the system throws the next exception:

[xlarsx]$ bzr qdiff

bzr: ERROR: exceptions.TypeError: argument 1 of qRegisterResourceData() has an invalid type
