Bug 263114

If you could attach one of the mail (in mbox format) that would be nice, but as you have privacy issues you can try and replace the text with bogus text and see if that still produces the error (the actual text should not matter) and attach that mail.

Else try and attach gdb to kmail when you have one of these freezes and post a full backtrace for all threads.

Hi, unfortunately replacing the private stuff ist very difficult, because the mail ist just very, very long. If there was a script somewhere which did this automatically?
I have tried with gdb, which did not went very well. I do not why. I just copied instructions someone gave me on another report.
But somehow after doing this, running Kmail without gdb again, the crash occured again, but somehow Kmail managed to start gdb this time. Both things I attach.

Application: KMail (kmail), signal: Aborted

* gdb kmail
* run --nofork
(kmail and most kde applications fork on start)
* threads apply all bt full

But the backtrace you posted showed where the code crashed, I just can't figure out why :(

Created attachment 56328 [details]
sample message that prompted crash on reply

While I'm not entirely sure that the bug that I reported is actually a duplicate of this one, I've attached a sample message that prompts a crash.  For me, this message caused a complete crash *EVERY* time that I tried to reply.  I do not observe the problem that this bug seems to indicate - that is, I have no problem *viewing* the email, only 'reply'ing to it.

I can't reproduce the crash with this email. However, it shows a curious issue when answering, the 4th line in the quoted signature isn't displayed correctly (the one with the fax number)

Is this still present with a resent version?

I can not tell, I have given up testing after a month intensive testing, since there was a low response rate on bug reports, no new beta (I am also not aware of a new beta, at least for Kubuntu) and with so many bugs, Kmail was not very much fun.

Closing due to lack of reproducibility.
