mokka-6 hangs on mac 10.8.5

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Mokka install from Mokka-0.6.2_MacOSX.dmg

What is the expected output? What do you see instead?
Mokka.app doesn't start

What version of the product are you using? On what operating system?
it is mac 10.8.5

Please provide any additional information below.

after failing to build mokka from btk source (because of vtk6 migration) i 
installed btk without vis_support and downloaded the normal dmg installer. I 
have a bad feeling that sth is wrong with my system, please see report 
attached. I used btk and Mokka before on this machine but it was with qt4.7, 
vtk 5 and os 10.8.4; Another thing are python wrapping errors, i posted it on 
the forum but now i am not sure may be it is connected. sorry for so many 
tickets

From your crash log, the error is in the video view. Do you configure Mokka to 
run with a video view at the startup? Can you move the file 
~/Library/Preferences/org.btk.Mokka.plist outside of the folder Preferences and 
launch Mokka again? 

On my side (Macbook Air 2013, MacOS 10.8.5), I have no problem to launch Mokka 
0.6.2 with the video widget. However, I did not try to load a video.

Regarding the building of Mokka and the migration to VTK 6. You can still 
compile Mokka with VTK 5 (and this is strongly suggested at this time). You can 
find the source of VTK 5.10.1 on the "previous release" section of the VTK 
website: http://www.vtk.org/VTK/resources/software.html#previous
However, at this time VTK 6 cannot be installed at the same time than VTK 
5.10.1. (The CMake script look for first VTK 6 before VTK 5)

For the Python wrapping error, I answered on the forum during the night and 
this should fix your problem. There is no link between the error in Mokka and 
the Python wrapping errors. They use the same core functions but they are not 
linked together.

Do not worry about the tickets or questions, it is a pleasure to answer.

thank you so much for your patience, i really appreciate it. 

I don't have org.btk.Mokka.plist may be because i never succeeded to start the 
program? Then i click on the icon it just bounces in the dock till i force quit 
it. Wrapping error is fixed!! very happy, thanks.

This is strange you do not find the file "org.btk.Mokka.plist". You said in 
your first message: "I used btk and Mokka before on this machine but it was 
with qt4.7, vtk 5 and os 10.8.4", so the file should be there.

Can you download Mokka 0.6 and try launch it instead of Mokka 0.6.2. There are 
differences in the compilation options between these two versions. Maybe It 
could help me to understand why Mokka 0.6.2 crashes on your computer.

Your guess was right, it runs!! I don't know what you changed in the 0.2 
version and why it is ok on your system and not on my.. If you need me to do 
sth that could be of some help to you, please ask. The 'I used btk and Mokka 
before' was in the beginning of 2013 and i first used dmg Mokka (probably not 
6.0.2) and was able to compile xCode from btk source.

wau it found old preferences as it has a list of old mdf files. where did you 
store them before? i definitely don't have  org.btk.Mokka.plist, i just checked 
again with find /usr

The file org.btk.Mokka.plist is in 
/Users/<your_username>/Library/Preferences/org.btk.Mokka.plist

Try the command 'open ~/Library/Preferences' (without '') in a terminal. It 
will open a new Finder windows. You should find inside the file 
org.btk.Mokka.plist

Thanks for this new crash report. Unfortunately, the error is the same, so this 
is not related to the configuration of Mokka's views but really in the 
initialization of the video view.

Right now, I think it is better for you to keep Mokka 0.6 until I found a way 
to solve this. Maybe the use of Qt5 in the next release of Mokka will fix this 
crash (The code of the video view will be redesigned to take advantage of new 
features in Qt5)

Sorry for this problem. I hope the use of Mokka 0.6 will be enough for your 
needs.

no worries, i am very happy that i can see content of the files and process it 
through python, so really thanks a lot for your help! and as i said if you need 
to test on my 'not working set up', just ask :). thanks, nicole
