Comment 1 David H 2006-06-21 09:50:50 UTC

Re-emerge and revdep-rebuild don't help. I'm now testing on another (less recently updated) gentoo system - more soon

Comment 2 David H 2006-06-21 10:53:46 UTC

Version 0.13 when re-emerged doesn't have this bug. I'll re-emerge 0.14 with debug to see if I can get a better backtrace. Now less urgent since 0.13 still works

Comment 3 David H 2006-06-21 22:05:09 UTC

Better backtrace (-O2, -g):

+ Trace 68985

#0 mop_get_next_ival
at planner-gantt-row.c line 962
#1 gantt_row_draw
at planner-gantt-row.c line 1345
#2 gnome_canvas_get_dither
from /usr/lib/libgnomecanvas-2.so.0


In gantt_row_draw, i=0, unit_ivals = 0, cur_unit = 0x6b6, and I wonder if cur_unit is being read before it is initialised...

adding 	cur_unit = (GList *)NULL;
at line 1226 of planner-gantt-row.c seems to fix it. 

This now needs someone who knows the code to see if entering mop_get_next_ival for the first time round the loop should have *start = 0.

I fear my fix might be masking a deeper problem

(sorry, no quick way to make a patch for this one line change)
