I was trying compiling and installing Owncloud client 2.0.2 with Qt5 on Fedora 23. Actions that have been successfully completed, but when I try to run the software, I get a segmentation fault. I was wondering if it was my fault or not.
Here the messages

Sorry, this kind of problems with self compiled bins can not be helped in the bug tracker. Please seek out for help on the devel mailinglist or the forum.

It was a backtrace I got while I was trying to move the Fedora owncloud client from Qt4 to Qt5 (I am the package co-maintainer).
I have just sent an e-mail to the devel mailinglist
