soffice.bin: /home/jmg/Development/libreoffice/symbols/vcl/source/window/toolbox.cxx:2286: void ToolBox::ImplFormat(bool): Assertion `item.maCalcRect.Top() >= 0' failed.
This crashes for me in any themed VCL plugin on Linux.
Well it actually doesn't crash with qt5 in the debugger, but without the debugger, so it looks like a timing problem.
It doesn't crash with gen. LO is master a few days old with some addition Qt only patches.
Interestingly the tooltip of the bar is "input bar", the tooltip of the button "expand formular bar".
It is reproducible for me, but given these weird circumstances...
