Subject: d4x crashes in strlen () from /lib64/libc.so.6

Package: d4x
Version: 2.5.6-2
Severity: grave
Justification: renders package unusable

d4x on attempt to process a link like
ftp://a5:70f32daf@dl010.filefactory.com/e/edbf5d055412df097e9ab4a16a886361/AB_091__E_.part05.rar

Please note that this particular link is already expired (i.e., login is incorrect and d4x survives). 
To get a fresh one, open http://www.filefactory.com/get/f.php?f=26f737dbc373854c4a38ac77 in a browser, 
wait 15 sec, click "Click here to continue to the download page.", wait another 15 sec and 
find the link under "FileFactory FTP -- Click here to download".

100% reproduciable here

Top of backtrace is
