[QGIS-Developer] plugin reload fail

[Borys Jurgiel]

Apparently my recent fix [1] wasn't enough and some modules are still not 
unloaded. Unfortunately I won't be able to work on it soon :(

As a workaround, maybe you can optimize the way you reload the whole QGIS? For 
example run QGIS in a loop (so you only need to press Ctrl-Q to reload), 
create a dedicated user profile (not burdened with other plugins), configure 
the startup project (with a test data), temporarily trigger one of the plugin 
actions in initGui (so the dialog you're currently working on opens 
automatically after reload).

Regards,
Borys
