kmail crashed with SIGSEGV in QString::replace()

[Michael Marley]

Binary package hint: kdepim

After a recent update, Kmail on Kubuntu Karmic x64 crashes very often when switching to the "Inbox" folder of either of the two Disconnected IMAP accounts I have it configured to check.

I see the issue as well - directly after startup. No accounts are configured to automatically update -> Its not related to fetching email.

[desert rover (desertrover)]

Same Issue. Crashes after finishing fetching new mail on startup.

[Arthur Schiwon (blizzz)]

Same problem on 32Bit system. Startup works, but it crashes when fetching email (no auto-fetching).

[Michal (mikeos)]

Same issue with kmail on karmic x64, when accessing IMAP folders. Appeared on upgrade to package version *ubuntu4. Downgrading kmail and dependent packages to *ubuntu3 makes it stable again.

dpkg -i libkleo4_4%3a4.3.1-0ubuntu3_amd64.deb libkdepim4_4%3a4.3.1-0ubuntu3_amd64.deb libkontactinterfaces4_4%3a4.3.1-0ubuntu3_amd64.deb libkpgp4_4%3a4.3.1-0ubuntu3_amd64.deb libksieve4_4%3a4.3.1-0ubuntu3_amd64.deb libmimelib4_4%3a4.3.1-0ubuntu3_amd64.deb kmail_4%3a4.3.1-0ubuntu3_amd64.deb

I can confirm this works on 32bit as well
cd /var/cache/apt/archives/
sudo dpkg -i libkleo4_4%3a4.3.1-0ubuntu3_i386.deb libkdepim4_4%3a4.3.1-0ubuntu3_i386.deb libkontactinterfaces4_4%3a4.3.1-0ubuntu3_i386.deb libkpgp4_4%3a4.3.1-0ubuntu3_i386.deb libksieve4_4%3a4.3.1-0ubuntu3_i386.deb libmimelib4_4%3a4.3.1-0ubuntu3_i386.deb kmail_4%3a4.3.1-0ubuntu3_i386.deb
Fixes the problem for me

Me too (Karmic 32bit)
downgrade to ububtu3 packages as suggested by mikeos and Nick Sandes made kdepim suite work again..
