Bug#388377: kontact: System often hangs (!) after opening 'New Mail' window

[Thomas Uttenthaler <tom@uttenthaler.at>]

Package: kontact
Version: 4:3.5.4-1
Severity: important


This happens not every time, but often. A few seconds after opening a
'New Mail' or 'Forward Mail' window (after having typed some letters), 
the system hangs completely. The magic sysreq keys  don't respond anymore. 
This happens since one of the last upgrades of multiple packages.  
After submitting this report, I'll try another kernel ...

any help would be very much appreciated, regards
tom
