pythonext crashes Mac Firefox 3.6.6 on startup

Upon downloading and installing zotero, and then pythonext 2.6.2 from zotero website my Firefox does not start anymore (Mac OSX 10.6.4, FF3.6.6).

The following error occurs:

/Applications/Firefox.app/Contents/MacOS/firefox-bin -p

On Firefox 3.5.10, the first error occurs as well, but then Firefox manages to start:


~/Desktop/Firefox.app/Contents/MacOS/firefox-bin -p
[Radek ~]$ Registering '@mozilla.org/module-loader/python;1' (libpybootstrap.dylib)
Registering '@python.org/pyXPCOMExtensionHelper;1' (pyXPCOMExtensionHelper.py)

self.message = message
Registering '@mozilla.org/module-loader/python;1' (libpybootstrap.dylib)
Registering '@python.org/pyXPCOMExtensionHelper;1' (pyXPCOMExtensionHelper.py)


and then things look fine (but again, it's FF 3.5.10).

Thanks,
Radek

Just an update: I'm using Zotero 2.0.3, and the pythonext version that disables my firefox is pythonext-2.6.2.20100203-Darwin_universal.xpi.

BTW going to the FF profile directory and deleting

extensions.cache
extensions.ini
extensions.rdf

does not restore FF functionality (still crash on startup). Creating a new profile is necessary.

Zotero plugin is not necessary to reproduce the crash, i.e., I create a new profile, go to zotero website and download pythonext and… so much for my FF profile.

Give the official pythonext build a try and see if that works. If not, you'll probably want to file a bug report at the pythonext site—my familiarity with the pythonext codebase is only superficial.

The official pythonext build did not work, I submitted a bug report https://www.mozdev.org/bugs/show_bug.cgi?id=22996
