Libre office crashed after making a new database. I created a new adatbase, registered it and then LO crashed. After restart LO repaired that new database and opened it in the tab "Forms". In going to the tab "Tables" LO crashed again. Reinstallation of LO did not help. I use: Windows 10, version 1511, LO version 5.0.4.2 (x64).
Could you try with version 5.1 to see, if the problem is still present? If it persists, try https://wiki.documentfoundation.org/UserProfile#Resolving_corruption_in_the_user_profile If even that won't help, a backtrace would be helpful for developers: https://wiki.documentfoundation.org/How_to_get_a_backtrace_with_WinDbg Set to NEEDINFO. Change back to UNCONFIRMED, if the problem persists. Change to RESOLVED WORKSFORME, if the problem went away.
Closing as WFM per direct email. 5.1 solved the problem.
