Hi Ludovic,
this is the backtrace from the original debian package pccsd 1.7.0-2 at the

Yes, sorry, this was a typo on my behalf.

With your patch, pcscd no longer crashes at hot-plug time... but it also
fails to use the reader:

So, as it seems, somehow, if openct is installed (and not running), pcscd will
not try to use its internal CCID driver? Is this intentional?
After applying your patch _and_ removing openct (no
/usr/lib/pcsc/drivers/openct-ifd.bundle/Contents/Linux/openct-ifd.so present
anymore), I was able to make it work:

So the patch seems to fix the segfault, but still the question remains: Why is
pcscd not using its internal CCID driver if OpenCT is installed (but not even
running) ?
Thanks again!
