Hello!

I figured out that the image-viewer fbi seems to be incomaptible to curl >= "7.29.0". The functions fb_cleanup() and fb_catch_exit_signals() print this error messages during regular application termination:

[code]
ioctl KDSETMODE: Bad file descriptor
ioctl FBIOPUT_VSCREENINFO: Bad file descriptor
ioctl FBIOGET_FSCREENINFO: Bad file descriptor
ioctl VT_SETMODE: Bad file descriptor
Oops: Segmentation fault
[/code]

Also fbi dies if invoked with "fbi --version" and dmesg shows this output (the version string is printed from version() and exit() is called immediately afterwards):
[code]
[ 1013.531194] fbi[1272]: segfault at 0 ip 00007f7d6ba4e4a0 sp 00007fffccc80690 error 6 in libcurl.so.4.3.0[7f7d6ba1c000+5d000]
[/code]

Questions:
Why does that happen?
Why does fbi depend/call libcurl?

Downgrading curl to a version below 7.29 fixed the issue.
Warning: Downgrade curl only for testing purposes! The latest release includes an important security fix, which could be trigged by web based programs on the client (e.g. webbrowser).

Additional notes:
The package of fbi is out-of-date 2.08 was replaced through 2.09, but this version also suffers the same problem. So I decided not to flag the package of fbi out-of-date, because this could just add additional, and unnecessary, round-trips.

The fbi project doesn't offer a upstream bugtracker, so I decided to report this issue at least here. Also I send the original program author a link to this report.

Thanks
