problem exists since update to kde 4.10.3
Qt: 4.8.4
KDE: 4.10.3 "release 561"
Kleopatra: 2.1.1

Kleopatra freezes after a few seconds

kleopatra gui freezes or some times freezes the hole desktop, so 'root' had to kill the process


Reproducible: Always

Steps to Reproduce:
1. start kleopatra (via gui oder via command line)
2. kde shows the symbol in tray
3.a) try to call different kleopatra menues
or 
3. b) do nothing , just wait (1 minute)

if i open the gui, kleopatra does not show any of the certificates (all windows are empty)

if startet via shell: after a few seconds i get a msg like the following (value for 'next size' differs):
*** glibc detected *** kleopatra: realloc(): invalid next size: 0x0865b810 ***

and kleopatra freezes. i had to kill the process.
Actual Results:  
i can't use the program.
