Description Michael Weghorn 2023-09-04 17:35:53 UTC
Steps to reproduce:

1) start the NVDA screen reader on Windows
2) start Writer
3) Tools -> Options
4) type "hello" in the newly addes search field
5) press Enter

Result: LO crashes due to an exception being thrown:

warn:svx:5688:9000:svtools/source/control/valueacc.cxx:953: Calling disposed object. Throwing exception:

Behavior is the same with qt6 on Linux, but not with gen (which doesn't have an a11y implementation) or gtk3 (which likely uses native gtk widgets).
