Crash when editing timesheet

[amantia]

Open a report for last week, open the editor for last week, add a new entry. For me it crashes reproducibly when selecting the project code for which I want to add an entry, although it survives inside valgrind with tons of QSFPM issues (it crashes once I close the edit dialog).

charmtimetracker --version Charm version 1.8.0-131-g270c

valgrind output:
