From: martin@steghoefer.eu [PATCH 16/16] Fix runtime problem with wxWidgets 3.0: Segmentation fault due to events arriving before initialization.

Browse Source 
"The dialogs LadspaEffectDialog, LV2EffectDialog and VampEffectDialog receive EVT_TEXT events before the dialog classes are properly initialized. To prevent this, a workaround was already in place, but was only active on Windows. This happens now on more platforms (including GTK). So activate it on the wxGTK with wx3.0, too."
