[Python-apps-team] Bug#952871: itstool: Segmentation Fault when Merging French Translation

[Francois Mazen]

Package: itstool
Version: 2.0.6-1
Severity: important


When merging the attached "fr.mo" file with itstool then it crashes with
Segmentation Fault.

Using other translation file like "de.mo" does not trigger crash.

To reproduce, use the attached files:
itstool -m fr.mo -o output.xml solfege.xml

GDB session:

gdb -ex r --args python3 /usr/bin/itstool -m fr.mo -o output.xml solfege.xml
