I think this problem has 'always' been there to some extent. A couple of
years ago on a version lost in the sands of time (probably 0.9 or so) I tried
spot removal on a picture from the Camargue with about 2000 flies needing
removal from the sky which rapidly realised the limitations of dt's spot
removal tool. For normal use of removing a few spots it works fine but for
the 1 in a thousand shots where I have some ridiculous level of spot removal to
do I drop out into gimp for that. Mea culpa for not raising it as a bug I
guess ...

Subject: [Darktable-users] Darktable crashes when using spot removal tool
Hi, all-
I've been experiencing this problem for a few months in dt, using both the
darktable-unstable PPA and the official Ubuntu package.
When I use the spot removal tool for more than just a few corrections, there's
a pretty good chance dt will crash. I haven't figured out how to reproduce it
every time, unfortunately. Here's the terminal output when the crash happens:
mjpatey@minimus:~$ darktable
Lua enabled
Could not attach to process. If your uid matches the uid of the target
process, check the setting of /proc/sys/kernel/yama/ptrace_scope, or try
again as the root user. For more details, see /etc/sysctl.d/10-ptrace.conf
ptrace: Operation not permitted.
/home/mjpatey/3328: No such file or directory.
backtrace written to /tmp/darktable_bt_I6845W.txt
Segmentation fault (core dumped)
And here is the backtrace referenced in the above message...
this is darktable 1.3+1223~g287d9e6 reporting a segfault:
/usr/share/darktable/gdb_commands:2: Error in sourced command file:
No stack.
Any idea if there's something I can do to prevent this crash, or is there any
further info you need from me to help determine the problem? Thank you in
advance for any light you can shed.
