Gfax keeps crashing right after start

[Master One]

Binary package hint: gfax

Fresh Ubuntu 7.04 installation, with Gfax 0.7.6-0ubuntu2 from the official repo.

At first it started normally, and I could setup all the necessary settings for using Hylafax as transport (to be used with a remote HylaFax server in my setup). After the setup was completed, it told me to restart Gfax, and since then it keeps crashing right after start with the following error message (shown when started from a console):

$ gfax

Unhandled Exception: System.ArgumentOutOfRangeException: < 0

I just compiled Gfax from source, and unfortunately it results in the same error. This problem only exists, if HylaFax is selected as transport, it seems to be working normally with efax.

I just installed Gfax, and it happens when I try to start it:

janus@mobileqcomp:~$ gfax

I'm not using Ubuntu right now. The problem was still there, the last
time I tried, and it could be fixed by fixing the reverse DNS entry
for the line I was using. A quite weird issue, especially because an
unproper reverse DNS entry should not let an app crash like that.

No, problem solved, it had to do with reverse-DNS-entry. I am not
using it any more, so I can not tell any more details about it, sorry.

by the way, andrea, is this still an issue for you?

[Andrea Marin (amarin)]

Hi Dimitrios,

excuse me for delay in my reply.
No for me is not still an issue because now i change fax server and i'm not using hylafax.

Thanks a lot for all.

Version: 0.7.6-9ubuntu1

This bug is still present in intrepid. Please reopen this bug.

The reason is because the Hylafax server is expecting both a USER and PASS, but gfax is only sending USER followed by a 'PASV' to initiate a file transfer:

220 blahblahblah server (HylaFAX (tm) Version 4.3.1) ready.
USER laterooms
331 Password required for laterooms.
PASV
530 Please login with USER and PASS.

At this point, gfax crashes with Unhandled Exception: System.ArgumentOutOfRangeException: < 0

Even after using gconf-editor to set /apps/gfax/transport/hylafax/password correctly, it still does not send 'PASS spider' after 'USER laterooms'

Thank you for taking the time to report this bug and helping to make Ubuntu better. I noticed the version of Ubuntu your using is in End of Life status. More information may be found at: https://wiki.ubuntu.com/Releases As well, the package version your bugging is updated in Lucid. Please update via http://releases.ubuntu.com/lucid/ repost a detailed error report, and update the bug status. Thanks!

[Jim Rorie (jfrorie)]

This is still a problem in Lucid. Same error exactly. It appears to start when you have an invalid hostname for hyla. When the address is correct, then we get the above posted error.

Rusivi2, see this bug for your problem

https://bugs.launchpad.net/ubuntu/+source/gfax/+bug/589748

It helped me solve the same problem you have.

[FiReSTaRT (dlyh)]

Sebastian,
Running the script did not help me. When I try to run gfax from the CLI, I get the following output:

Unhandled Exception: GLib.GException: Icon 'gtk-info' not present in theme
  at Gtk.IconTheme.LoadIcon (System.String icon_name, Int32 size, IconLookupFlags flags) [0x00000] in <filename unknown>:0

  at gfax.gfax.Main (System.String[] args) [0x00000] in <filename unknown>:0

I am also attaching gfax.txt which is strace output when running it from the CLI, with only my username scrubbed out and replaced with "username"
