SciLab 5.5.2 exception when selecting file/open from menubar

0.4.10-release-0-g2be9148 gcc dbg lin affected
SciLab 5.5.2 from rapps
I noticed this earlier already for 0.4.7-rls-tests & 0.4.8-rls-tests &0.4.9-rls-tests.
I did not test the version earlier than that yet.

The app is based on Java.

When we select from the menubar file->open
the app throws 2 exceptions, logs one of them to the screen into its console:
EXCEPTION_ACCESS_VIOLATION with "uigetfile" function.
access_violation.png

ros does not log anything helpful then, so I retried with breakOnFirstChance, we see both exceptions, but the stacklogs won't tell us much:
access_violation.log
Java-obscurity I guess.

Sidenote: The save file function fails very similar:
"EXCEPTION_ACCESS_VIOLATION with "uiputfile" function."
