rar2fs crash

[hasse69]

I got a crash in rar2fs when scanning my media directory with plex, 

I have tried this version 1.16 and trunk with unrar 4.0.7 and 4.2.4 both dies on the same file:

#sudo -u plex rar2fs -o allow_other /mnt/data1 /mnt/data1_rar2fs

I just noticed that the file header is corrupt in those files when trying to unpack
manually. Is there anything I can do to make rar2fs skip this files?

--seek-length=1 solved it, sorry for not reading the manual better. =)

Thanks for the issue report.
Even though --seek-length=1 solves the problem for you does not mean rar2fs should
crash simply because some header is corrupt. So your report is very much valid.
I will start by sending you a private e-mail with some additional questions before
digging deeper into this issue.

A possible fix has been sent to submitter and verified to resolve the issue (also attached).
An official version will be committed to trunk after a few more tests.

Case closed.
