Description Jacob Wintersmith 2007-11-25 15:52:39 UTC

Version:           1.9.6 (using KDE KDE 3.5.8)
Installed from:    Ubuntu Packages

I have an IMAP account I wish to delete. When I attempt to do so, Kmail reliably crashes immediately after I press the Ok/Apply button. Backtrace is pasted below.

I started kontact, set up two imap Profiles with the mail-component, restarted kontact and tried to remove both profiles again. After confirming that by clicking OK, kontact crashed. When I try to restart it, it suddenly displays the Crash-Dialogue again.

Comment 3 Tommi Tervo 2007-12-03 15:51:17 UTC

Be aware when testing this bug, I lost all emails :-(
I added second imap account to same server where my primary email account is and then I tried to delete that second account by highlighting it and pressing folder->delete folder. Kmail started to do something and then it displayed a message that cannot delete that folder. I pressed continue and then went to settings -> configure kmail -> accounts and removed second account. Then kmail purged my primary email folder.

I confirm this bug.

And a backtrace WITH debugging symbols, for KDE 3.5 branch, looks like this:

Comment 7 Thorsten Staerk 2007-12-18 14:07:52 UTC

the function removeFolderAux is described as 
/** Called from KMFolder::remove when the folderstorage was removed */

However, the crash occurs when removeFolderAux tries to access the storage:

static_cast<KMFolder*>(parent)->storage()->updateChildrenState();

Comment 8 Thorsten Staerk 2007-12-18 14:12:39 UTC

Created attachment 22608 [details]
this patch removes the problem

Comment 9 Thorsten Staerk 2007-12-18 20:00:25 UTC

SVN commit 750129 by tstaerk:

Do not crash when deleting an imap account.
imap accounts can point to their uppermost folder recursively.
When deleting the folder's parent, first check it is not the folder
itself.
