Comment 3 for bug 1542190

Just to be sure: if you completely uninstall the custom palette on Windows (and any bkp or swp files in the palettes directory which could be a result of editing the already installed GPL file in a plain-text editor), the crash on exit no longer occurs?

Did you install the custom palette which triggers the crash on exit into Inkscape's shared 'palettes' folder, or into the one for the current user's palettes ( %APPDATA%\inkscape\palettes )?

JFTR - no crash on exit with Inkscape 0.91 r13725 on OS X 10.7.5 after installing the custom palette provided by the reporter; modifying a copy and substituting 'Collectivites' with 'Collectivités' works ok too (no crash on exit).
Locale used by Inkscape for the tests on osx: 'en_US.UTF-8'
