Control: retitle -1 Errors when reading dicomdir file: "No images found" / "Loading: DICM Error reading file"

Hi Gerd,

thanks for the prompt feedback.

Ok, so I may have been a little bit quick with my conclusion.

I tried to import a file named "dicomdir" which I can view with other
DICOM viewers (namely invesalius and dicomimageviewer) by using File
-> Import File (specify) -> via "DICOM 3.0 via (X)MedCon" without
medcon or xmedcon installed. So I expected that the commandline tools
are required but missing.

The error message in the popup is:

  AMIDE WARNING

  Can't read file .../dicomdir with libmdc/(X)MedCon

The popup actually popped up twice. (BTW, it is very annoying that I
can not copy and paste from that error message. Especially if they're
longer as in the case with using the dcmtk backend, which throws
errors, but seems to work somehow in the end.)

On the commandline where I started amide, it shows the following messages,
but only once:

  Mar 04 12:29:49 log[31810]: error: No images found

  (amide:31810): (X)MedCon-WARNING **: Loading: DICM Error reading file

So I've installed xmedcon, opened that file with it and it gave me the
same error messages on the commandline:

  Mar 04 12:41:43 log[5807]: error: No images found

  (xmedcon:5807): (X)MedCon-WARNING **: Reading: DICM Error reading file

So it's either an issue with the medcon library or PEBKAC. I'm
reassiging this to the according library package.

Please feel free to close this bug report if libmdc2 is not expected
to handle dicomdir files (mine contains/references data from two
examinations).

amide as well as xmedcon seems to work well on single frames from an
X-Ray video in DICOM format, but I haven't found a way to view the
whole video with either of these tools.

Yes, I noticed that, too, but that worked (more or less) without dmctk
being installed. There's also a hard dependency on some dmctk library.
(I did recognize that one but not the medcon library, sorry.) So I
expected that the library suffices in that case.

Yeah, but IMHO that's irrelevant here. That task package pulls in tons
of packages I don't need. I just need an DICOM viewer.
