Segmentation fault after updating Liferea from 1.8.8 to 1.10.9

[vakuum]

I updated Liferea from 1.8.8 to 1.10.9 and now I get a segmentation fault during start up:

$ liferea --version
Liferea 1.10.9

$ which liferea
/opt/liferea/bin/liferea

$ export XDG_DATA_DIRS=/opt/liferea/share:$XDG_DATA_DIRS

$ liferea --debug-trace

Segmentation fault (core dumped)

The backtrace from the core file:

$ gdb /opt/liferea/bin/liferea

(gdb) backtrace

Start up works fine after adding a NULL pointer check to line 1590 in src/db.c:

    if (id != NULL && g_str_equal (node->id, (gchar *)id))
        return TRUE;

Sorry, should have worked on this sooner. I somehow overlooked the issue. I added a similar fix as you suggested. Thanks for the detailed debugging!
