-- Information about the crash:
- What I was doing when the application crashed:
For unknown reasons, the program closes several times over several hours, during continuous conversion of file names.
But never on the "rename", but after returning to the main screen and you select the next directory.

Or CPU or memory is not overloaded.

The crash can be reproduced sometimes.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
