File open hangs if folders present in target directory

On my pclos 32-bit (KDE 4.9.2) machine, the Folder view plasmoid, Dolphin and file open dialogues in applications all freeze for 30 seconds if the default directory contains sub-folders. This applies the first time the dialogue is opened for each run of the application.

Opening kwrite from konsole reveals one extra message which does not appear on my 64-bit (KDE 4.8.3) system. This appears at the end of the 30 seconds:
Code: Select all
QProcess: Destroyed while process is still running.


I presume this means a waiting or looping process is being killed after a 30-second time out. At the end of that time the file and folder icons appear as expected. I would like some guidance on what the process could be and why it might hang in this way.

Any help welcome.

Are you able to attach a debugger to one of the "frozen" processes and generate a backtrace to see where it is stuck?
The 30 seconds timeout indicates that it is probably a D-Bus timeout (at which point it becomes a question of which external process is frozen)
