Re: g_io_channel_read_to_end read just 998 chars, not more

[frederico schardong <frede sch gmail com>]

This is very strange. Yesterday I have got 998 characters from the
g_io_channel_read_to_end, but today I have compiled with and without
the if to show the error, but every time I'm getting 0 characters from
the channel! I don't know what can cause it, because nothing has been
changed unless the if.
