When I try to launch game, the plugin and xulrunner crash :

in the journal the error is :

--- Running report_uReport ---
Server side error: '"Validation failed: error validating 'core_backtrace': error validating 'path': string \"\/home\/jpprade\/.mozilla\/firefox\/7b5ncr87.default\/extensions\/[email protected]\/plugins\/npquakelive.x64.so\" contains illegal characters"'
(exited with 1)

I check the path it exists ;

ll /home/jpprade/.mozilla/firefox/7b5ncr87.default/extensions/[email protected]/plugins/
total 3544

-rw-r--r-- 1 jpprade jpprade 1792789 17 févr. 2012 npquakelive.x64.so

do you know any workaround to fix this error maybe (it dont't like the "@")? thanks !
