Symbols seem to be missing (bug 476518?)

Reproducible: Didn't try.

What I did just before the crash:
1. Hit Ctrl+Q

Actual result: crash (If Breakpad hadn't come up I would probably not have noticed it :-/

Expected result: normal closedown

I saw the same yesterday and believe it is the same as reported in Bug 476349.

Possible, but hard to tell, with this build without symbols before the 6th level down the stack.

After reloading (to get the UA string) then Ctrl+Q shortly thereafter - no crash.
Originally, loading yesterday after nightly upgrade, not much action the next day (at most, dismiss one alert) and finally Ctrl+Q - crash.

In both cases, I had deleted an "Untitled calendar" created at every startup (that's a different bug). FYI, all my calendars are .csi files, one of them readonly-remote, the others local.

The patch that caused this crash has been backed out from 1.9.1 branch, see bug 476349 comment #17. Sunbird build 20090203 should not crash anymore.

OK, (here on Linux at least) it didn't.

Hm, with the lack of symbols in my Breakpad/Soccorro reports mentioned above, and the fact that that other bug is mostly about Tb (and Fx), I lack the necessary expertise to VERIFY the dupe. All I can say is that the bug seems to be absent from recent Sb-trunk nightlies (since the date of comment #6 above).
