Some more details. This is the latest output from "strace" as running against
an existing gnucash process, just before hitting the "File->Quit" option:

And the referred file contents were as follows after the crash on shutdown:
"""
$ cat /tmp/gnucash.trace

* 17:12:33 WARN <gnc.backend.dbi> [gnc_module_init_backend_dbi()] No DBD
drivers found
"""
That seems to match quite well the crash on dbi_shutdown_r reported
earlier on, so despite only logging a WARNING, the root cause for the
crash on shutdown may lay there.
So I took one additional step: trying to provide gnucash with some valid libDBI
implementation for DB backends. Prior to that, I only had the following
installed regarding DBI:
"""
$ dpkg --get-selections | grep dbi
libdbi-perl install
libdbi1:i386 install
"""
And then I just installed the following:
"""
$ sudo apt-get install libdbd-mysql
"""
After doing so, I can now happily start and quit gnucash with no further
crashes, SIGSEGVs or any other woes of the same kind.
So recapping what's on this Bug, it looks like gnucash as shipped by Ubuntu
14.10 needs the following two additional packages to work fine and not crash at
all:
"""
- python-gnucash: helps with avoiding gnucash to barf errors on startup, but
causes gnucash to crash when quitting
- libdbd-mysql (or probably any other SQL-related DBI library): on top of the
above, it makes gnucash avoid a SIGSEGV on "dbi_shutdown_r" on shutdown, and
therefore quit cleanly
Hope this helps others and the package maintainer as well.
