gpg hangs

[wilk]

gpg --with-colons --list-config hangs forever after diplaying

cfg:version:1.4.14
cfg:pubkey:1;2;3;16;17
cfg:cipher:1;2;3;4;7;8;9;10;11;12;13

gpg cannot be killed after that, even with kill -9. This freezes any program using gpg (gnus in Emacs in my case) and even prevents shutdown and reboot.

I'm running Ubuntu 13.10 x86-64 on a Microsoft Surface Pro.

I ran a strace, and it seems to hang at

open("/dev/bus/usb/003/005", O_RDWR

lsusb indicates that this device is

Bus 003 Device 005: ID 1286:2044 Marvell Semiconductor, Inc.

which it seems is the Wi-Fi chip.

Is this running as root or as a user account? I would hope your user account would not have write access to this device in this fashion.

Thanks

I have the same problem running as root. I discovered that blacklisting the mwifiex_usb (responsible for wifi and bluetooth if I'm not mistaken) module "fixed" this problem: gpg doesn't hang anymore and the computer can now be shut down. Of course you lose wifi...
