Created attachment 67204 [details] strace.log LibreOffice dies just after start (just splashscreen is shown). I removed ~/.config/libreoffice/ and ~/.libreoffice/ just to make sure that my config isn't the source of it. Error message is: terminate called after throwing an instance of 'com::sun::star::uno::DeploymentException' Use revision 25ebe01cf39eba32e8e65995d709e5e803b627a1 (More ::rtl::OUString to OUString in avmedia) with cherry-picked fix https://gerrit.libreoffice.org/628. Note: I reported this into #54858, but asked to fill new bugreport.
Petr, can you run LO from within gdb and see to produce a backtrace ("gdb .../soffice.bin", then "run", and once it reports the uncaught exception do "thread apply all backtrace"). (From what you write I gather you built LO yourself. Did you build it completely afresh? What installation are you running, "make dev-install" or building and installing an installation set?)
Note there was still a problem with bug 54858 that still caused a com::sun::star::uno::DeploymentException upon opening "File - Properties... - General", fixed now with <http://cgit.freedesktop.org/libreoffice/core/commit/?id=e8b79f29a66b0528ad9ba2023930d3ba23915022> "fdo#54858: DocumentDigitalSignatures::initialize can be called with 0 args now." Your crash at start-up is likely due to the same cause, though it is unclear to me under what circumstances the relevant code would already be executed during start-up.
(In reply to comment #1) I'm sorry, I forgot to run "make dev-install" after "make" (silly mistake). After that everything works.
