[pkg-lxqt-devel] Bug#927905: lxqt-qtplugin try to load the wrong version of libfm-qt

[Alf Gaida]

Package: lxqt-qtplugin
Version: 0.14.1~1-gc122cbd-1
Severity: important
Tags: patch

Dear Maintainer,

lxqt-qtplugin try to load libfm-qt.so which is strictly a dev symlink - the right choice would be libfm-qt.so.6.
This brings up the poor Qt file dialog instead of the LXQt one when opening a file. 

For Buster a sufficient solution would be hard wiring the needed so-version.

Thanks to @wxl (Lubuntu Team) for spotting this.
