Hi everybody,

thanks for working on my previous bug, but it improved only a little bit on my
system...
If I want to change the exifrotation on a file for the first time, it works, if
I want to change it on this file for a second time, digikam freezes... after
killing and restarting, the rotation is done... I tested iton several PEF,
always same behaviour, first time it works, resetting it doesn't work...
I started digikam from terminal, no significant output...

greets mike

I think it relevant of last code done by Marcel about icon-view Qt4 model/view
port. This problem do not only appear when you set thumbs orientation, but also
when you assign tag/rating from pop-up menu. Can you confirm it ?

Actually not, rating works fine... and exifrotation works also fine, if it is
an picture which hasn't been rotated before... it only freezes if I try to
exifrotate an image which has been rotated by digikam before, not necessarily
in that session...
exiv2 on the commandline does it without any problems, on the same image
multiple times...

I have the assumption that in the code for writing metadata to files and for
adjusting the Exif orientation something is touching structures that may only
be touched from the main event loop. This leads to failed assertions at random
places interacting with xlib. This can also be related to 193508.
I will have to audit the code paths touched from there.
