What can I do to get theide to log it's state & call-trace when this error happen?
(A last resort, because it is very intrusive, will be to run theide itself in DEBUG
but I would first like to try easier / less hassle methods before I go there.)
I guess you should build new binary with symbols (export CXXFLAGS="-ggdb -O3 -ffunction-sections -fdata-sections";export LDFLAGS="-ggdb"; make -j 4; make install) and enable core dump in your system.
After crash use gdb to find out the place when theide fails.
