My hardware platforms are quite diverse. I don't think it's irrelevant, that's why I asked. If you don't provide this information, we won't be able to check which code paths are involved Given you are the only one to reproduce the issue, please provide a backtrace of a crash so that we can proceed further. -- Aurelien Jarno GPG: 4096R/1DDD8C9B aurel...@aurel32.net http://www.aurel32.net
