Crashing of Firefox and Thunderbird when saving mail attachments.

[Teunis]

I just upgraded from Feisty to Gutsy and regretfully the crashing of both Thunderbird and Firefox when attempting to save an E-mail attachment has not been fixed.
When I start these programs from the terminal I get the error message: Segmentation fault
This does happen on for example .wav files but not on a .doc file.

Everything does work fine when I run either program as sudo...

Any ideas?

Re: Crashing of Firefox and Thunderbird when saving mail attachments.

gut feeling...
nothing to do with neither thunderbird, nor firefox.
it's going to be some permission setting on some other file or directory...
you might want to try and strace the execution of one or both applications.
like so:

strace thunderbird > /tmp/thunderbird.strace 2>&1

you can then attach that file to a post here, so that we can take a look at it.

this is the only thing that crops up...

I assume the missing init.d files might be a reason for the crash?

Re: Crashing of Firefox and Thunderbird when saving mail attachments.

don't think so.

i tried on mine and i have the same output.
though after the "process detached" message, my thunderbird starts up all right...

is this the bit where you save an attachment?

usually, when normal user can't do something while user root can
it means there's a permission issue somewhere...

if you say firefox has the same behaviour...
it's got to be something thunderbird and firefox do/have in common.
like some shared library or something...

sorry i can't be of any more help.
i'm pretty sure you problem has nothing to do with thunderbird and firefox specifically.

Re: Crashing of Firefox and Thunderbird when saving mail attachments.

It's (for me) getting weirder, I found out the crashing does not happen with some more common formats/extensions.
For example saving an attached .txt, pdf or jpg file goes fine, with a wav Thunderbird crashes unless started as sudo...
