Bug#1023722: qrenderdoc crashes immediately

[Bernhard Übelacker]

Dear Maintainer,
this issue was also discussed upstream in [1] [2].

There the reason was given, that running the application
inside a KDE plasma session makes Qt pick up some KDE
shared libraries (KDEPlasmaPlatformTheme.so),
which does its own GL interactions, which is
not expected by qrenderdoc at that time.

A package built with upstream patch [3] makes qrenderdoc
not crash at startup inside a KDE plasma session.

Kind regards,
Bernhard

Bug#1023722: qrenderdoc crashes immediately

[Zeb Figura]

Package: qrenderdoc
Version: 1.22+dfsg-1
Severity: important

Dear Maintainer,

qrenderdoc crashes immmediately when run:

whatsit@camazotz:~$ qrenderdoc
Segmentation fault (core dumped)

A gdb backtrace suggests it's crashing trying to call the host glGetString,
which is NULL for some reason. I don't know why this would be. This is 64-bit
qrenderdoc; 64-bit glxgears works fine. Using `renderdoccmd capture` and
`renderdoccmd replay` also works fine.

This does not happen with the upstream renderdoc 1.22 package available at
.

gdb backtrace pasted below:
