already fix in 4.13.2
Comment 3 Gregor Mi 2015-02-28 11:25:00 UTC
Hi, the autosave folder problem can also occur with version 4.14.4:

I composed a mail with a 1 GB attachment which made kontact/kmail crash after hitting the send button. Now there is a 1,4 GB file in the /home/gregor/.kde4/share/apps/kmail2/autosave/ folder which causes a crash when attempting to start kontact or kmail.

Renaming the file from {7695bac9-2ccc-49a7-979d-61e4669e152d} to __{7695bac9-2ccc-49a7-979d-61e4669e152d} caused another crash on startup. Removing the file completely fixed the problem.

Should this bug be reopend or another report be created?
Comment 4 Laurent Montel 2015-02-28 12:53:25 UTC
Do you have a backtrace ?
Comment 5 Gregor Mi 2015-02-28 13:37:35 UTC
I got this on the console:

terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc
*** KMail got signal 6 (Exiting)
unnamed app(19074): Communication problem with  "kmail2" , it probably crashed. 
Error message was:  "org.freedesktop.DBus.Error.NoReply" : " "Message did not receive a reply (timeout by message bus)" "
Comment 6 Gregor Mi 2015-02-28 13:46:54 UTC
When I start kmail from krunner or kicker (instead of the console) the whole desktop becomes unresponsive here and there until the data is processed.

I can reproduce it by simply putting a random 1 GB file into the autosave folder by hand.

Similar scenario: If I put an mp3 file there (5 MB) kmail opens and the message compose window opens which displays garbage in the editor and then kmail freezes with 25% CPU load. The console shows

** (process:19199): CRITICAL **: enchant_dict_check: assertion 'g_utf8_validate(word, len, NULL)' failed
and every 30 seconds another line is added.
