Sorry for the delay in my answer, but I waited quiterss/0.13.3+dfsg-1
migration to jessie.

Unfortunately the SIGSEGV (at least for me) is here also in this
version.

To investigate more on this, I thought I can build it with debug
informations on and play around with gdb and/or valgrind.

I tried these steps:
* apt-get build-dep quiterss
* dget 
http://ftp.de.debian.org/debian/pool/main/q/quiterss/quiterss_0.13.3+dfsg-1.dsc
* debuild -us -uc

And I confirm that the package gets built.

I'm not a packager, so I wasn't able to build it with debug informations
turned on playing around with debian/ files and using debuild. 

I launched it under gdb even without debug info, and it segfaults
reliably when clicking on "Next unread" when
* There is no article opened in the right pane, AND
* There are unread articles in the left one.

This is gdb output:

Reading symbols from /usr/bin/quiterss...(no debugging symbols found)...done.
(gdb) run

Do you need "set solib-search-path" or "set sysroot"?
