This is on a SeaMonkey trunk build for Kanotix, clobber, at startup.  I have no idea what's causing it.

Here's my build config.

Steps to reproduce:
dist/bin/seamonkey

Expected results:  SeaMonkey loads.
Actual results: crash

Comment 1

[Daniel C]

This is the error I was getting last October in bug 312105. I narrowed it down to debug cairo builds only. There are a few pages in that bug that consistently crash. If you can't reproduce with a non-debug build then I'll dupe that bug to this one, since the other one is messy.

Comment 2

[Christian :Biesinger (don't email me, ping me on IRC)]

well, the assertion is in cairo code, and assertions have no effect in non-debug builds, so it's no surprise that only cairo debug builds are affected.

Comment 3

[Alex Vincent [:WeirdAl]]

Yeah, unable to reproduce in opt build.  :(  My debug build is therefore unusable.
