I went on some little investigation about the problem below and, I will try to
give an explaination.
It is, probably, due to the fact that upon forcing a rebuild, the directories
present both on the disk and in the tagcache files are not processed again to
save time. In this case, if a directory is removed, the rebuild algorithm
fails noticing it because it checks if all the remaining directory pathnames
(one by one) are already cached (and they are) but doesn't verify that in
cache there is something "more" than on disk. Of course, by deleting the
tagcache files the incoherence disappears.
I tried uncommenting line 2427 in tagcache.c:
2426. case Q_FORCE_UPDATE:
to remove files before rebuilding and, of course, it works.
What about changing the current option in the configuration menu to something
like "Update tag cache" and introducing a new "Force tag cache update" that
also removes current cache files?
