By default, Bugzilla does not search the list of RESOLVED bugs.
You can force it to do so by putting the upper-case word ALL in front of your search query, e.g.: ALL tdelibs
We recommend searching for bugs this way, as you may discover that your bug has already been resolved and fixed in a later release.

Fix the showfoto build for work the image plugins and the sidebar color histogram

The sidebar color histogram was crashed due to using liblcms together liblcms2 and which have even functions.

So for fixing, the library liblcms must be loaded in the first order.

digikam_LoadCPU.patch

Digikam has yet one very interest issue, that is CPU heating-loading on 100% at work all functions.

After digging in the problem I linked its reproduction with the two factors:
1. execution the custom events postEvent(this, new TQCustomEvent()) from the Threaded object to itself;
2. KDirWatch

After replacing the postEvent(this, new TQCustomEvent()) call in the LoadingCache object by this patch I have removed the loading in most cases, but that still appeared in execution showfoto with the commandline arguments, so digikam completely works fine and the started cleanly showfoto also works fine.

Digging to the issue reproduction with the commandline arguments I have stopped on it disappearance-appearance in LoadingCache::LoadingCache() just at creating KDirWatch().
