Version:           unspecified (using KDE 4.5.4) 
OS:                Linux

I upgraded from KDE 4.5.3 to KDE 4.5.4 today, and now Konsole crashes upon startup.

Reproducible: Always

Steps to Reproduce:
1. Type "konsole" at the command prompt.

Actual Results:  
2. The konsole window appears briefly, then disappears.  The following is output to the console where konsole was launched:

$ konsole
[psy@sable:~]$ KCrash: Application 'konsole' crashing...
KCrash: Attempting to start /usr/lib64/kde4/libexec/drkonqi from kdeinit

Warning: connect() failed: : No such file or directory
KCrash: Attempting to start /usr/lib64/kde4/libexec/drkonqi directly

I then get a crash dialog with the following backtrace:

Expected Results:  
2. Konsole should have started up without crashing as usual
