@Germano0 Which Qt version is the client using? You should see that in the settings dialog or when running client with owncloud --logfile -

@dragotin Maybe the client should ship its own Qt on Linux like on OS X and Windows?

[guruz]

@Germano0 Any info?

[Germano0]

@guruz I just pinged the bugreporter. Let's wait for a reply

[guruz]

@dragotin @jnweiger Do we have Qt5-based RedHat packages somewhere lying around as alternative for @Germano0 ?

[dragotin]

@guruz our packages for Fedora 22 compile against Qt5: https://build.opensuse.org/package/live_build_log/isv:ownCloud:desktop/owncloud-client/Fedora_22/x86_64

[guruz]

@Germano0 Does it work with those packages?

[Germano0]

@guruz What do you mean exactly?

[guruz]

@Germano0 We think this is a Qt4 problem.
We also have Qt5-based ownCloud client packages for Fedora22
https://software.opensuse.org/download.html?project=isv%3AownCloud%3Adesktop&package=owncloud-client

[Germano0]

@guruz I am still waiting for a reply from the Fedora bugreporter

Another user experienced the problem. I asked him to show me the installed qt libs. Hereunder his reply:

Yes, but I remember now that I have done a "dnf upgrade" during this session, so this may be inaccurate:

@Germano0 This does not help. It's fine for a system to have both qt4 and qt5 installed.
What you need is an ownCloud client with Qt5 and then see if that is fixed.

[guruz]

@Germano0 Does this still occur with your Qt5 based Fedora package?

[Germano0]

Hi @guruz , I just asked to the person who filled the Fedora bugreport. Soon I wil receive a feedback

[Germano0]

On Fedora bugzilla the bug is marked as fixed due missing feedback from bugreport creator. I assume it as fixed even here
