I guess your problem comes from the ACS driver.
Try to run pcscd inside gdb to generate a backtrace.
Do something like:
$ sudo gdb /usr/sbin/pcscd
(gdb) set args -dfa
(gdb) run
then start opensc-tool
pcscd should crash
in gdb use:
(gdb) backtrace
Yes, you are right: the crash is in the IFD handler.
For the records, here the backtrace:

I cannot fix it, regrettably I do not have enough time to learn
everything needed... :) It is a pity, though, because the driver has
been written by David Corcoran, a name I read often in pcsc-lite
source: it could have been a device more, just like ACR38U.
I can't find a Debian package providing this driver.
Do you confirm the acsAcr30 driver is NOT packaged by Debian?
So, sorry for the noise, feel free to close the (non-)bug.
Thanks for your support and your work.
You are welcome.
Bye
