Mozilla "save as" options no longer work: they pop up the file picker dialog box, but no directories are available. You can get moz to crash by clicking on "show hidden directories". This is mozilla-1.0.1-2.7.2. To reproduce, pick a site (www.google.com), right click on the image, and select "save image as ..."; you get the bad dialog box. This also seems to be a config munge or some sort of version incompatibility; this occurred only after I ran up2date this morning. Removing my ~/.mozilla directory allows it to work properly. This may be the same bug as reported in Debian Woody (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=158041&repeatmerged=yes ) I'll attach the gdb backtrace from the crash as well.

Well, I did a binary replace on files in my .mozilla dir; apparently the XUL.mfasl file is not completely compatible between upgrades. Deleting this file seemed to fix the problem, so that's a possible workaround.
