segfault with -t switch

[MichalSt]

Binary package hint: usbutils

when I connect my mobile phone to usb lsusb starts to segfault with -t switch.
I tried to debug it down to the source code and found following:

when I: "cat /sys/bus/usb/devices/2-3.1/bMaxPower" (I assume this node is on of my mobile phones')
it responds with empty line. lsusb is reading this "" value and incorrectly process it in lsusb-t.c:245.
while(r) is true (r=-1 in such case) and It keeps replacing "\n" beyond the bottom limit of the buffer.
When it accidentally hit a "\n" to replace it tries to rewrite it and causes segmentation fault.
