Created attachment 71821 [details] backtrace I have a docx file which makes Libreoffice crash immideatly. Sadly it is a private file so I cannot attach it. However, I am willing to send it privately to interested developers. The backtrace is attached of: /opt/lodev4.0/program/soffice --backtrace Reisekostenabrechnung_Graduates_DBAG.docx I can open this file with the Libreoffice Version of Ubuntu 3.6.3 and the 4.0 ppa which is at 4.0.0.alpha1. However, the official 4.0.0.beta1 crashes.
Taking, again an error under LanguageTag::canonicalize() Apparently fixed now because we don't call liblangtag anymore for known locales. Anyhow, need to figure that out for future cases.
For me this is fixed with libreoffice-4-0~2012-12-19_09.46.59_LibO-Dev_4.0.0.0.beta1_Linux_x86-64_install-deb_en-US.tar.gz
Marking as FIXED as both bug reporter and Eike have said it's solved.
