Hello Bernhard (Übelacker), thanks for your response!
| Is pdfsig on your system really not crashing if firefox is installed? this is my guess, because I've looked into the code and for verification it gives either a code path /etc/pki/nssdb or something in the personal profile to the nss library used. I haven't yet tried if just installing Firefox is enough to create one of the both needed path. | Maybe you could run following command in a terminal to get a backtrace Done, see below. Segfault as expected within libnss3.
