[Libreoffice] Writer delete row gives a segment violation

Hi,

In the current master I got a segment violation, when I create a table in
Writer and the delete a row.

The bt:
Program received signal SIGSEGV, Segmentation fault.

In version 3.3.3 it was not a problem.

Is this only on my machine, or a real regression?
