This appears to be a race condition...repro's on exactly the same pages but only 30% of time.  It's always difficult to give repro steps for race conditions.

Could you dig anything out of the traces?  I can see that ff is doing some kind of name resolve, but I can't see what functions it ultimately crashes on.  Any sense of what symbol files I am missing?

we need a step by step instruction how to reproduce this in the bug
summary. and a symbolized backtrace. Without those elements its not
really likely that we can process your crash.

BTW, the instructions should be easy to apply for intrepid.

You received this bug notification because you are a direct subscriber

Status in “firefox-3.0” source package in Ubuntu: Incomplete

Bug description:
Basically the same stacktrace on most pages.  Is NOT tied to Flash (have tried w Flash installed and removed).  Not usable, using Firefox under Wine as workaround (ick!)
