** Description changed:

+ #############
+ SRU information:
+ Impact: All imap users will probably experience this bug at some point. Very unpleasant.
+ How the bug was fixed: Upstream created a patch to stop an infinite recursion in the imap mail retrieval code.
+ Patch: http://websvn.kde.org/?revision=1074179&view=revision
+ How to reproduce the bug: There isn't any hard testcase, but in general resuming from sleep or loosing your internet connection triggers the bug.
+ Regression potential: Small, kdepim upstream is pretty good about such things.
+ #############
+ 
  I quit kmail but then I notices two instances of kio_imap4 where running, using 100% cpu.
  I am not sure if this hanging of kio_imap4 started before I quit kmail or  after.
  No other program uses mail.
  
  Versions:
  ii  kdelibs-bin               4:4.1.4-0ubuntu1~intrepid executables for all KDE 4 core applications
  ii  kdepimlibs5               4:4.1.4-0ubuntu1~intrepid core libraries for KDE PIM 4 applications
  ii  kmail                     4:4.1.4-0ubuntu1~intrepid KDE Email cli
