More infos of KCrash/gdb and glxinfo.
This might be a duplicate of #102423 or #103234.
(But did not want to pollute these if they were unrelated.)

713 index_max_size = (indexbuf->width0 - index_offset) /
At this point it looks like variable indexbuf is NULL.
"bt full" would suggest this too:
#7 0x00007f78c278d2b0 in si_draw_vbo (ctx=0x5600dec29f30, info=0x5600dec6b1...
...
indexbuf = 0x0
So I cannot reproduce this and was hit just once.
But it could be related to the not so long Qt 5.10 update in Debian testing.
I took a core dump if there are more questions.
All debug symbols are available as far as I see.
Related could also be that the core file is of a size of 3.5 GB so that
might have led to the NULL pointer.
Attached is a file containing the more infos of KCrash/gdb and glxinfo.
