Hi Roman: I did the cleaning you suggested. After that I started Darktable
as

darktable -d

DT crashed again.

cribari@darwin3:~/personal/photo/software/darktable$ darktable -d
[defaults] found a 64-bit system with 7730816 kb ram and 4 cores (0 atom
based)
[mipmap_cache] cache is empty, file
`/home/cribari/.cache/darktable/mipmaps-5adeeaa995f8ecf7e64bb1fe188c8f3ec6160f28'
doesn't exist
[exiv2] Directory SubImage2, entry 0x0111: Strip 0 is outside of the data
area; ignored.

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.

directory.
backtrace written to /tmp/darktable_bt_636XNX.txt
Segmentation fault (core dumped)
cribari@darwin3:~/personal/photo/software/darktable$

The backtrace file it generated contains the following:

cribari@darwin3:~/personal/photo/software/darktable$ sudo cat
/tmp/darktable_bt_636XNX.txt
this is darktable 1.5+2135~g3be1611 reporting a segfault:

/usr/share/darktable/gdb_commands:2: Error in sourced command file:
No stack.
cribari@darwin3:~/personal/photo/software/darktable$

Darktable also crashes when I start it the normal way (via Unity).

Is there anything else I should try? Suggestions are welcome. Thank you. FC
