Choosing "preferences" freezes my machine
I'm on Ubuntu 9.04 beta, but originally installed Zotero in Ubuntu 8.08. Firefox 3.0.10. Whenever I choose "preferences", my entire machine freezes. Sometimes I get some the preferences window visible first. Not even ctrl-alt-F1 gets me a terminal, but the mouse does move. I have to hard-reset my machine.
I understand that Zotero by itself couldn't do something that drastic, but obviously it is triggering a bug somewhere else (in Gnome?). The datadir was standard and all the permissions there worked.
I'm fine now, so whatever. But you can email me if you think you have a fix, or before you go out of beta.
If you'd like to help find the cause, you might also try running Firefox with debug output enabled just to see what the last line is.
