Bug#428323: libgempc430: Causes pcscd to segfault on startup
Selon Mark Brown [EMAIL PROTECTED]: Package: libgempc430 Version: 1.0.1-5 Severity: grave Justification: renders package unusable When a Gemplus smart card reader is connected and this package is installed libgempc430 segfaults on startup on my PowerPC based system: I tried to reproduce the problem on a PowerPC iMac with Ubuntu. I can use the reader without problem. I also compiled and installed pcsc-lite 1.4.2 (Ubuntu has an older version) and I can't reproduce the problem. Please note that I've only got access to this device as a result of being at Debconf and may therefore be unable to reproduce in future. I do not have Debian installed on this machine and do not plan to install it. So I would need your help and some more debug info. Can you rebuild the libgempc430 package and install the driver directly so the debug info is not stripped? When you start pcscd inside gdb use the pcscd arguments --foreground --debug Thanks
