            Bug ID: 131210
           Summary: UI: Laguage Options: editing 'Date acceptance
                    patterns' crashes whole application
           Product: LibreOffice
           Version: 6.4.1.2 release
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org

Description:
Calc: Tools > Options > Language Settings > Languages
changing 'Date acceptance patterns' by typing a y (year) hangs further keyboard
input and crashes application within a minute (50sec)

Steps to Reproduce:
1. Language of 
- user interface: is set to English (USA)
- locale setting: changed from EN to German
- default currency: automatically becomes 'default EUR'
- date acceptance pattern: becomes: 'D.M.Y;D.M' (for day.month.year)
2. deleting 'D.M.' part of the pattern
3. typing a y for year shows "error/stop" Symbol 
an no further keyboard input possible
4. resetting the user profile and application (to factory settings, both ui and
user) in/and using safe mode
but self-shutdown after reset to factory settings now last longer up to
90~110sec after hanging
btw: the application did never "restart" by itself, but i had always to run it
once again time

Actual Results:
can move Options-window by mouse, but no keys are accpeted
system load increases significantly (notebook fan) for about 50sec
than all application windows disappear 


Expected Results:
should not crash, should be able to continue typing, changing pattern


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes

Additional Info:
for whole dialog setting (if that's a reason), pls see screenshots
