Comment 42 for bug 372103

I've made a Firefox build with some logging here:
https://<email address hidden>/

If you have something in the clipboard that causes a crash (in Thunderbird or
other Mozilla apps), then run this build and try pasting into a
contenteditable element such as in attachment 345137.

The build is based on trunk (a few days ago), so I suggest either back up your
profile or "mkdir ~/tmp/new-profile" and run with "-profile ~/tmp/new-profile
-no-remote".

It shouldn't crash but will log some info like this:

** (firefox-bin:17547): WARNING **: atom_name is NULL for targets[0] == 0x78
** (firefox-bin:17547): WARNING **: xatom is 606 for GdkAtom 0x78
** (firefox-bin:17547): WARNING **: xatom 606 name is text/plain;charset=UTF-8

Hopefully the logs might provide some clues as to what is happening.
