I'm seeing the same issue with FF 3 RC1 (hardy-proposed). Getting a backtrace isn't possible as there is no -dbg or -dbgsyms version of the package available.

[Thomas Zander (thomas-e-zander)]

Same here with FF3 RC1. Slightly more verbose stacktrace attached.
Pedro, is there anything more I can do to provide useful info?

[Bert Van de Poel (bhack)]

It still happens on hardy 64 with firefox 3.0.1 but opera doesn't seem to have the same problem (or at least not that often)

Just booted the pc for the first time this morning, started the update manager and up popped this crash.

Using Intrepid AMD64.

I'm still getting this crash, even though I'm on Intrepid without libflashsupport. According to bug 192888, this should be fixed. Is this really a dupe, or has bug 192888 been marked incorrectly?

flashplugin-nonfree/intrepid uptodate 10.0.1.218+10.0.0.525ubuntu1
ia32-libs/intrepid uptodate 2.2ubuntu13
