Fedora 21 texstudio fails with symbol lookup error

I just installed Fedora 21 on a laptop, and among other things I installed Texstudio. While the install seems to work fine in general, I get absolutely no reaction from this single program. I have tried the following: 1. Remove and reinstall. 2. Remove and reinstall using .rpm provided at webpage of Texstudio. 3. Open a single .tex-file. None of the above give any reaction whatsoever. Texworks works fine. Being an inexperienced user I do not know whether or not this will be of any help, but simply typing texstudio in the terminal gives the following: texstudio: symbol lookup error: texstudio: undefined symbol: _ZN20QFutureInterfaceBase13setThreadPoolEP11QThreadPool
