(Keywords: hang) 

User Agent: Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:44.0) Gecko/20100101 Firefox/44.0
Build ID: 20160202150527

Steps to reproduce:

OS: Fedora 23
Everytime I insert an USB smartcard reader[1] (that I received with EsteID -DIGI-ID E-RESIDENT) *while* Thunderbird is running, it will start immediately using 100% CPU load.
To exit from Thunderbird, I have to kill the process.

Instead if I first insert the USB smartcard reader, and then I start Thunderbird, everything is okay. But sometimes if you unplug the smartcard reader while Thunderbird is running (normally), it will crash. I have sent many crashreports with the automatic report tool.

The service that handles the smartcard readers is pcsc-lite-1.8.15-1.fc23.x86_64

I own a Thinkpad that has an integrated smartcard reader and it has never gave me problems with Thunderbird, so the problem relies in the fact that you plug and unplug an USB smartcard reader.

I experience an identical problem with Firefox
