[digikam] [Bug 374712] New: Preview image does not work any more from thumbs view

            Bug ID: 374712
           Summary: Preview image does not work any more from thumbs view
           Product: digikam
           Version: 5.4.0
          Platform: Other
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Thumbnails
          Assignee: [hidden email]
          Reporter: [hidden email]
  Target Milestone: ---

In the current 4.4.0 appimage (64bit Linux, Ubuntu 16.04 amd64) since importing
the last batch of images from my camera, I cannot enter preview mode (with one
image enlarged and the rest as thumbnails at the top) any more.
When I try, simply nothing happens, except that the toolbar options are toggled
respectively ("Vorschaubild" becomes active).

Restarting digikam fixes this usually, but then sometimes the menu and toolbars
are gone.

I just experienced this again with the current 5.4.0 appimage (Ubuntu 16.04)
after fullscreen viewing + tagging (rating) a number of images. Repeatable.

I can rate about 10 images with the keyboard and then fullscreen view gets
stuck at the current image, I cannot go to the next or previous image any more,
when I exit the preview back to thumbnails, I cannot enter it any more (no
image shown).

The console shows the following last messages:

digikam.metaengine: DateTime => Exif.Photo.DateTimeOriginal =>
QDateTime(2017-01-19 15:25:28.000 CET Qt::TimeSpec(LocalTime))
digikam.database: Scanning took 14 ms

digikam.metaengine: Exif color-space tag is sRGB. Using default sRGB ICC
profile.

"/tmp/.mount_GaIDR1/usr/share/digikam/profiles/srgb-d65.icm"

...come from the content of AppImage ISO9660 file system mountem in temp
directory by the kernel.

It's strange that ICC color profile is not found, because all data must be
embeded in bundle.

What's "ls /tmp/__MOUNT__POINT__/usr/share/digikam/profiles/" give when digiKam
is running ?

Well the ICC files are there are expected... So why files cannot be found by
Color Management code in DK...

Please disable color management for IconView to confirm that problem is here.

Done. So far, no more crashes.

Also I'll continue using 5.5.0 appimage from now, to see if this bug is still
there.
