Description philippe.quaglia 2016-08-19 17:13:03 UTC

I use the «item» «edit geolocalisation» tool. I the tool, I select a set of images and slide them to the map to geolocalise them. I can do it once or twice, and then digikam freezes, and all the computer freezes too. The pointer does not have any more effect, only the keyboard keys can be used. It allows me to open the dash and logout, it is the only way I found to get out.
It happens all the time, but after one or two set of pictures have been geolocalised.

I have run digikam in backtrace, to get the information, but as everything was frozen, it was difficult to get the data. The only think I was able to do was to take a picture of the screen, as attached. You can see in the background the geolocalisation tool, with images selected. Every thing has frozen when I have slided the selection to the map. In the terminal, you can see the backtrace, I only get on line: «thread 0x7fff5abb9700 (LWP 15230) exited».


Reproducible: Sometimes

Steps to Reproduce:
1.Geolocalise pictures, once or twice
2.
3.

Comment 2 caulier.gilles 2016-08-19 17:16:38 UTC

Run digiKam on gdb as explained here and give us the backtrace :

Comment 3 philippe.quaglia 2016-08-20 08:22:08 UTC

Already did it, as explained above. See the picture. As every thing is frozen, does not found any other way to get it than taking a picture of the screen...

Comment 4 Maik Qualmann 2016-08-20 20:44:47 UTC

What happens when you use Marble and play with it? I think it's a problem with your graphics drivers.

Comment 5 caulier.gilles 2016-08-21 08:17:42 UTC

Not reproducible here too, under Linux, MacOS and Windows.

As Maik said it sound like a video card driver problem on your computer...

Check your system

Comment 6 philippe.quaglia 2016-08-21 16:26:08 UTC

Thanks for your answers. That's strange, because it works well with Digikam 4.11 (I'm now working with 4.11 for géolocalisation, and 5.1 for the other stuff). I do not have any graphic cards, just the integrated graphic driver from the processor.
I will play with marble and tell you if i get the bug too.
Regards.

Comment 7 caulier.gilles 2016-08-21 16:52:57 UTC

I'm not sure to 100%, but i think Marble has plugin based on OpenGL. This can be the problem.

Comment 8 philippe.quaglia 2016-08-22 17:37:24 UTC

Hello, I managed to make additional test today, and I managed to have a complete backtrace this time. I explained: I improperly used the term «freeze», because in fact, the keyboard is still usable, while the mouse moves the cursor but does not make any action. So I opened a system window, and 2 terminals. I launched digikam with gdb with one terminal. When the freeze happened, I have been able to make a backtrace, and to kill digikam, to be able to recover the mouse control and to retrieve the backtrace. Previously, my only way out was to logoff, and I was loosing the backtrace information.
Therefore, is here the backtrace I get (hope this helps, it's ununderstandable for me...).
Regards.
