Description Ryan Winter 2007-12-18 00:00:54 UTC

Version:            (using KDE KDE 3.97.0)
Installed from:    Compiled From Sources
OS:                Linux

I have added gmail to kmail using the DIMAP protocol. All seems ok, but after downloading about 25 messages, the download process stalls.

I then closed kmail and launched it again, which results in an application crash. I will try to recompile the application with debug so I can post a stack.

Below is the backtrace for the crash. I'll try and do some investigation into what is happening.

Comment 3 Thomas McGuire 2007-12-21 15:22:34 UTC

SVN commit 751262 by tmcguire:

Create the groupware interface in the kernel constructor, and
only delay the D-Bus registration until KMKernel::setupDBus()
is called.

This is needed because KMFolderCachedImap::readConfig accesses
the groupware interface, and it is called before setupDBus().

This probably fixes
