In short whenever a synth plugin is added and the config window reopen
the plug-in isn't shown (as if it had "disappeared").
Because Michael can't seem to reproduce it (see the bug thread), I was
wondering if anyone else on the list is also experiencing it to try... I
guess that could be helpful to find some sort of criteria.
I have just built from SVN 16.13 Qt 4.8.7 and am running Fedora 23 64 bit.
