I've let a lot of photos build up over the past few months and finally
got around to tagging them today. This is the first time I've used
1.2.0 for anything more than a bit of browsing. This particular problem
with the disabling of the tag tree is worse in 1.2.0 than in any
previous version I have used.

For whatever reason, DigiKam seems very sluggish today; maybe that
is why more than half of the time this happens from the main
browsing window:

 1. I select some photos (that have never been tagged before), say
    about ten of them. I click the first thumbnail image (well, the
    box around the image) and then Shift-click the last image to
    select the range.

 2. I check a couple of tags in the tag tree in the right-hand panel.

 3. I click the next image I want to tag. This starts to apply the
    tags set in 2. to the images selected in 1. At this point the
    tag tree is still enabled. I just select one image, though
    selecting a range will have the same effect.

 4. I start to move the mouse from the image towards the tag tree
    to select a new tag. While I am on my way over there, the tag
    tree will suddenly become disabled, just as if I has not selected
    any images.

 5. I deselect the image from 3. and select it again. Now the tag
    tree is enabled and I can select a new image.

So, more than half the time, I have to select images twice to make
sure that the tag tree is enabled.

Here is my theory:

While DigiKam is applying tags to images in the background, it
was designed to disable the tag tree and then enable it when the
tagging was complete. However, it is doing it backwards: it is
enabling the tree when it starts and disabling it when it finishes.
Some sort of Boolean flag is being applied incorrectly.

OK, it's just a theory with no evidence to support it other than
the observed behaviour of the GUI. However, the fact that the tag
tree is enabled while I am making my second selection and then
suddenly appears disabled for no other apparent reason would seem
to suggest that it is caused by the background task that is applying
the tags to the previously selected images.

Anyway, it's bugging the proverbial out of me today, so I thought
I would write it up at great length...again.
