Dear list,
I got an assertion in stable (1b596e92) for the second time today. It
happened while selecting text (first time with Shift+Arrows and second
time with the mouse).
I don't remember seeing it before: if it wasn't introduced recently then
maybe it was hidden by the fact that I did not use instant preview
before. I cannot think of anything particular in my settings apart from
instant preview on, only one document displayed.
I opened gdb after the first crash just in case. I don't know how to
reproduce it, the second crash happened when I was no longer paying
attention. I am keeping my gdb session open for a while if you would
like me to extract more relevant informations than the trace below, just
ask.
