[Solved] Rstudio segmentation fault

Whenever I start R-studio, the program quits instantly with a segmentation fault. The backtrace is posted below:

R still works fine in the command line. I am using rstudio-desktop-bin from AUR.

I tried searching for solutions, but I could not immediately find any help. Any pointers on how to solve this are welcome, as i have no experience with Qt or C++. If you need more information, please tell me.

Should I report this to RStudio or is Qt5 to blame?

Hi Sam_DM!

Try this PKGBUILD: https://gist.github.com/chmue/7baeb5892f46c43b3000

Worked for me...
