evolution-source-registry crashed with SIGSEGV in g_hash_table_lookup()

Raising a new bug after discussions on Bug #1494804 suggested that this was a different issue as the one documented under #1494804 originated in 15.10.

I don't know what I did to stimulate the problem. An error report prompt appeared one day.

I'll answer the same questions from Bug #1494804 here in case they are relevant.

> what accounts he/she has configured, whether any are from Ubuntu Online Accounts or GNOME Online Accounts?

I have a personal GoogleMail imapx account created though the Online Accounts Service and an ews OWA account linked to my work exchange server.

> whether it crashes also when he/she runs the evolution-source-registry from a terminal manually?

It seems to have worked OK when I ran /usr/lib/evolution/evolution-source-registry. The output I can see is as follow (with my addresses changed manually to <email address hidden> & <email address hidden>):

> whether running the source registry under valgrind will also reproduce the crash (it can happen that other timing, due to all slowness caused by the memory checking, will not trigger the crash, but also that the valgrind will log about the issue and will keep the application running). The command might look like (I do not know exact location of the executable, thus it can differ in your distribution):
  $ G_SLICE=always-malloc valgrind /usr/libexec/evolution-source-registry &>log"

As I know jumping to memory based on what could be uninitialised variables is a bad thing. It seems possible that the tool is mistaken about the initialisation though.

Possibly related bugs from the old one were #1200934, #1200819 & #1383852. I can see now that Bug #1383852 is already marked as affecting me so perhaps this is a duplicate?
