File property dialog of a dll-file may contain unprintable characters in ros, but does not on XPSP3

0.4.11-RC-36-gc5204e3 gcc dbg

Reproduction steps
-install Mypal 27.9.4 from rapps
-navigate into its binary directory %program files%\mypal
-open file properties dlg of the file xul.dll and select the Version-tab

Expected result
The "description" field should be empty for this very specific file, like in xpsp3_ok.PNG

Observed result
The "description" field contains unprintable characters that appear like memory garbage to me.
0.4.11-RC-36-gc5204e3__UnprintableChars_xulDescription.png
0.4.11-RC-36-gc5204e3__UnprintableChars_xulDescription.log contains nothing.

Side-note: Some other fields are affected as well for this very specific file.
