GammaRay connects and timeouts

[heatblazer]

Hi I have build gammaray with gcc 6.7.1 and tried to attach and debug a small toy project of mine with Qt. However I got some errors that can't found in the wiki:

warning: process 14332 is already traced by process 14322
ptrace: Operation not permitted.
No symbol table is loaded.  Use the "file" command.

See <https://github.com/KDAB/GammaRay/wiki/Known-Issues> for troubleshooting

This link (https://github.com/heatblazer/zzx) is my repo for a smiple Qt application with QWidgets, I am starting it and it's running and I want to attach via GammaRay but however the above problem occurs. Also in the pointed wiki I didn't found anything regarding GAMMARAY_LAUNCHER_TIMEOUT.
