Re: Fedora and LV2

I believe I have found the problem.

It seems in Fedora it is possible to install the plugins without
installing the guis. The plugin guis are in a seperate package
(lv2-calf-plugins-gui). If this package is not installed I also get the
crash.

Try installing the above package - then rosegarden should work.

Rosegarden should include a check for this case.

Thanks to Chuck for his support here
