I am having a problem where Wireshark begins capturing packets, and then stops
(updating packets in real time, and data being transfered). Sometimes, but not
always, some 'Ethernet [Malformed Packet]' frames appear in the window.

The following messages appear in the console:

Warn Error "Less data was read than was expected" while reading:
"/tmp/wiresharkXXXX0e1H3j"
Warn Error "File contains a record that's not valid" while reading:
"/tmp/wiresharkXXXX0e1H3j"
(this last one repeated every second)

My guess is that due to a read of only partial data, wireshark desyncs with the
file format, 
thus all subsequent packets reads are erroneus.
In fact, doing "Reload this capture file" does load much more data.
