Issue description

Hello,

first of all thanks a lot for developing and maintaining FreeCAD! Great job :-)

Unfortunately I have a problem importing images in the Image workbench. According to this or this tutorial video, I should be able to view or import pictures from the Image workbench without further preparation. But when I press the respective buttons, it has no effect. Namely, the commands show up in the Python console (see screenshot 1), but no file selection box opens. What am I missing?

I am using Xubuntu 20.04.5 (amd64) and FreeCAD 0.20.1 installed via system Snap-Store. So nothing funny there. If you need more information, just let me know.

Some more observations:

the built-in self-test (freecad --run-test 0 &> test_output.txt) finds 39 errors (see screenshot 2 and attached output). I fail to find anything related to image import, but I may be wrong
in this video (see 3:15), importing an image creates an ImagePlane object. This doesn't happen on my system

Thanks again for your support and have a great day!

Georg

Update:

I deinstalled the snap and

installed via apt-get
- the installed version is 0.18.4 -> outdated
- image view and import works as expected
- self-tests fail altogether, because some library is not found
- deinstalled again
downloaded the AppImage from https://www.freecadweb.org
- installed version is 0.20.1.29410
- image view and import works as expected
- self-tests result in only 1 error (see attachment)

So either there were many bugfixes (including image import) between 0.20.1.29177 (Snap) and 0.20.1.29410 (AppImage), or there is an issue with the Snap package. I suspect the latter.

For now I will stick to the AppImage as it solves the initial problem.

In the future, you need to sign-up to the forum and create an issue. It saves you and everyone work primarily because development versions are way ahead of minor versions. Can you confirm with Snap 'edge' ?

snap refresh freecad --channel=latest/edge # switch to edge/nightly version
snap refresh freecad --channel=latest/stable # switch back to stable version

Edit: moving to FreeCAD-snap repo temporarily to declutter FreeCAD/FreeCAD issue queue

Hi luzpaz,

sorry for the late response! But I first wanted to finish my project before messing with the working AppImage installation.

Can you please explain what you mean by "sign up to the forum and create an issue"? Which forum, and why not this issue tracker? Thanks in advance!

Ok, I followed your instructions for the newest snap version: Here's what I did:

re-installed FreeCAD from snapstore
launched FreeCAD, created new document and confirmed that image view and import still have no effect --> don't work
updated to edge/nightly build via sudo snap refresh freecad --channel=latest/edge --> freecad (edge) 0.21-g4904ab50
launched (edge) FreeCAD, created new document and checked if image view and import work --> work as expected :-)
ran self-test via freecad --run-test 0 &> test_output.txt. Result see test_output.txt

Here's the full version info:

Saw this in the log file:

Traceback (most recent call last):
  File "/snap/freecad/344/usr/Mod/PartDesign/TestPartDesignGui.py", line 55, in __call__
    self.test.assertIsNone(diag, "Dialog box could not be found")

AssertionError: <PySide2.QtWidgets.QMessageBox(0x556166856440) at 0x7f12f2adc400> is not None : Dialog box could not be found

I'll test my local version and confirm
