Crash when importing SSP files with TLM systems

[robbr48]

Creating OMS models with TLM systems works fine. Loading an SSP file with a TLM system, however, crashes the GUI when trying to open the library entries.

I have done extensive debugging, and I could pinpoint the crash to this line (ModelWidgetContainer.cpp, 7312):

pModelWidget->show();

Importing SSP with only non-TLM systems works fine.

I was able to pinpoint the problem more accurately. It crashes in GitCommands::getGitStdout, on the line gitProcess->waitForFinished(). It seems like there is a conflict with the QProcess stuff and the signal handlers in OMTLMSimulator. I will disable these for now, at least during the modelling stage.

Thanks for the debugging. It helped to fix this quickly!
