The curious thing is I have this package (last upgraded on 6th Jan) and no problems with any of these apps, so there must be another factor involved.
Looking at the drakconf.real script further, it seems the crash happens when PCC tries to build all the pages of links to the actual applications after probing what is available on your particular system, so the reason some see it and not others is likely to be a matter of what is installed in your system. I suspect this means hardware, drivers, and possibly applications used for certain functions, rather than a fault in PCC or even webkit itself. Tracking it down will mean those of you who have this problem giving full system specs including all hardware, drivers, and any software that isn't on a standard install. If a common pattern emerges that will point to the problem. As one who doesn't suffer the problem I wish you well in the search.
