[Qgis-developer] QGIS crash during testing of my plugin

Tue Oct 14 02:15:46 PDT 2014

Hi everybody,

I'm developing a Python plugin with several submodules (like MMQGIS).
I create a BaseDialog class to create each dialog and some functions
to fill the dialogs.
When I try to call the second method QGIS crash and it return this logs.
Maybe I should create a ui file for each method and don't use the
BaseDialog class to create my interfaces?

QGIS died on signal 11[New LWP 28114]
