[gutsy] kmail often crashes during drag'n'drop operations from/to imap folders

[Martin Nowack]

Binary package hint: kmail

Using kontact with kmail I often drag and drop mails from one imap (ssl) folder to an other.
Often this results in a sigsegv, but not always, currently I have no clue to reproduce it:

current version of kmail is 3.5.7enterprise20070926-0ubuntu2

And the stacktrace is:

(no debugging symbols found)
Using host libthread_db library "/lib/tls/i686/cmov/libthread_db.so.1".

[Richard Birnie (rbirnie-deactivatedaccount)]

Does this crash still occur with more recent versions of kmail? If so could you please provide us with the following information:
what version of kubuntu do you currently use?
What version of kmail currently displays the crash?

If you are able to induce the crash at will could you please install the package kdepim-dbg then induce the crash. This will fill in all the lines that say 'no debugging symbols found' on the current trace and hopefully help us track down the problem

[Martin Nowack (martin-nowack)]

I changed to intrepid with kde 4.1.1. Currently their are no such problem.

Sorry, I can't say anything anymore about kde 3.x.

[Richard Birnie (rbirnie-deactivatedaccount)]

thanks for the quick response. In the absence further information I'll close this report. If similar problems emerge in KDE4 then feel free to file a new report
