Happened a second time while deleting the same cyrillic spam mail.

it was either this

... or this spam that caused the crash

This is connected imap, not disconnected/cached imap, isn't it? 

Connected yes.

In addition I must add I don't only see crashes while deleting Russian
spam, it crashes when deleting some other mails too. Usually often
when you delete a lot of them quickly.

I got a lot more crashes while deleting email. Sometimes it also doesn't
delete a mail and just says "Moving failed" (and if you retry a few times
it eventually crashes). In one case it also quitted without calling kcrash.

Anyways, installed debuginfo now and i got this backtrace.

Same Problem here (Kmail 1.8.2, KDE 3.4.2 Level "b"). Using IMAP (connected) and it crashes every time I delete mails (not only russian spam *g*) or when I try to move a mail to another folder.

For me, witht this, kmail is unusable at the moment :(

Andi: I've just had the kmail online-imap maintainer look at this, he says your crash is unfixable without a redesign (that we are currently busy with).  Workarounds are to not use search folders, not delete mail during mail checks, and try to delete mail in smaller quantities.

Tobias: as this bug happens on every move and delete for you it must be different to Andis. Please attach some backtraces with kdepim3-debuginfo.rpm installed - which is on the DVD or on FTP install sources.

I have the same problem (kmail crashes while deleting a dozen of e-mails on IMAP = not always) with kdepim3-3.5.0-12 on SLES10. 

Here is my backtrace:

System configuration startup check disabled.

Andi: I've just fixed #135882 which is related due to a logic error in the imap bodystructure parser code.  Please can you try again with 10.1beta>4 to test.  I am unable to reproduce this crash using your spam though.  

Tobias, Martin: Your bug is a different bug to 'specific emails (Russian spam) crash kmail'.  Do the workarounds I mention above help at all?

Sorry!

It seems that my crahes were results of a misconfigured IMAP-Server (is sth. like that possible?). I deleted an imap-account and now it'S working like expected. No crashes anymore...

I am unable to reproduce this any more :(

I have observed this with first versions of SLES10 (preview?) but I have'nt seen this for a long time now. Thus for me this is no longer a problem ;)

It also went away here.

Tobias: no, it's a KMail problem.  It hasn't gone away, you were just lucky so far.  We fixed some individual bugs in KMail but the design problem still stands.  If you have more crashes, please post backtraces here.

Andi: even with those russian spams?

Please reopen if still an issue.
