Folder management Segfault in Apache

[Ilya]

Hi, I just noticed that I can no longer manage my folders.
Whenever I click on folders in IMP it takes along time to time out and than
apache  segfaults:
[Sun Feb 10 23:21:20 2002] [info] [client 192.168.0.1] send timed out
[Sun Feb 10 23:21:27 2002] [notice] child pid 28519 exit signal Segmentation
fault (11)

I can however choose and list folder from top right list of folders.
here is gdb:
