Version: unspecified (using KDE 4.5.4) OS: Linux I just updated to kdepim 4.4.9 using KDE 4.5.4 and now when composing an email kontact hangs after a while. No more interaction is possible even though the cursors keeps blinking and the window repaints itself when it was hidden (using no desktop effects). However, killing kontact seems to be the only possibility to get a working client back. So it's a data loss of the mails opened in the composer. Reproducible: Sometimes Steps to Reproduce: Answer to a mail, write half a paper and then watch it hang forever... (it happened for the first time in the moment of sending a mail). Actual Results: hang Expected Results: continue editing/send I started kontact from konsole: http://kde.pastey.net/144697 After killing with -9, it said: meyerm@yavin ~ $ *** KMail got signal 15 (Exiting) (process:20899): GLib-WARNING **: g_main_context_prepare(): main loop already active in another thread kontact: Fatal IO error: client killed QCoreApplication::postEvent: Unexpected null receiver
Aah! It seems to happen all the time when I try to send a mail :-(
Does it happen if you try to reproduce the issue in KMail instead of Kontact ? If not, you could try to use gdb to gather more informations. There's a brief howto on this page: http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_with_GDB in konsole: *gdb --args kontact --nofork *run When kontact stops being reactive, CTRL + C then: *thread apply all backtrace *kill (to terminate the kontact process) *quit (to quit gdb)
Thanks for reacting that fast. It also happens in standalone kmail. http://kde.pastey.net/144699 Since I saw messages about missing addressbooks etc. I want to add that choosing the receipient within kmail work flawlessly. But the problem can be triggered immediately by simply hitting send. I'm happy to provide you with more data if needed.

One more question: is Akonadi running ? (try to run kaddressbook, if you see your contacts, it is)
Thank you, I'll happily check. While all my contacts are still available in KMail they are missing in KAddressbook. Since my KOrganizer is also working normally, I didn't realize that something is wrong. There is not even an addressbook shown on the left column within KAdressbook, so your guess about a not running akonadi seems to be quite good ;-) In my "resources" system settings there was no addressbook either. I readded my .vcf-file and set it as standard. This didn't help. I then choose to add a "new" addressbook in KAddressbook and tried using the "KDE Resource" and my .vcf as "VCard file". Neither worked. So I guess this means KAddressbook is no longer able to work without Akonadi at all? I don't have any System Setting which contains the string "akonadi". Since I have no clue about Akonadi I finally chose to use the akonadi_console, removed the duplicated entries and clicked "restart". Nothing changed. I used the menu "Server->stop" which was acknowledged by a notification saying the correspondent applications won't work any longer. Shortly thereafter the akonadi_console browser showed some data (including my addressbook)... Ook (why after stoping...?), now KAddressbook shows the contacts again and kmail can send mails again. So far, so good. Thank you. I meanwhile updated to KDE 4.5.5 and now it looks like Akonadi is beeing started automatically again. But despite me not messing around with any Akonadi-settings myself (perhaps by accident?), I thought that kmail 1.x is still "Akonadi-free" - why is it affected by a missing Akonadi-daemon? And why is it then simply hanging instead of complaining? Thank you so far - I got a lot of mails to write ;-). BTW: Should I prefer pasting long outputs inline over pastebins on b.k.o in the future?
You're right, KMail in kdepim 4.4.9 doesn't use Akonadi. However, kaddressbook does since 4.4.0. That's why Akonadi *must* be running or anything that tries to access your addressbook will hang forever (what you initially reported) Side note: Always paste backtraces directly in the comments. That makes the bugs triagers happy. When using an external service to paste some text or pictures, you have no guarantee that your data will be there forever. Closing this report since everything is now working as expected.
