Product: kdenlive
Version: git-master

OS: Linux
Status: REPORTED
Severity: normal

Variables for the stack trace
SUMMARY
When I open Kdenlive and add 5 videos, it asks me if I want to update the
project profile while it already starts generating thumbnails. I click yes (so
it changes to 1920x1050, 60 fps) and Kdenlive crashes.
The stack trace is below, the variables are in the attached file. The reason
seems to be that
> double consumer_aspect = mlt_profile_sar( mlt_service_profile(
> MLT_FILTER_SERVICE( filter ) ) );
returns NaN and then breaks the following computation, yielding SIGFPE.
