>Description:
gwenview hangs up while creating thumbnails for a particular folder:

$ gwenview /my/photos/directory
kbuildsycoca running...
ASSERT: "false" in thumbnailloadjob.cpp (571)
ASSERT: "subjobs.isEmpty()" in thumbnailloadjob.cpp (567)

<< here the UI freezes

The thumbnails begin to appear and it hangs up at different points failing to display the next thumbnail and frozing the UI, so it's not due to a specific image (the directory contains approx ~450 jpeg photos 1600x1200). The gwenview process is displayed in `top` in "ucond" state, the CPU is quite loaded at the moment it hangs up, the scheduler is ULE and the threading library is libthr if it matters. The system and ports are all up to date at the moment the bug is filed.
