xournal crashes on "save as pdf" if text input has been used when annotating a pdf

[khul]

Binary package hint: xournal

If I open an existing pdf using xournal and add some text using the keyboard, then xournal dies abruptly when I try to save the modified pdf. A "pdf" file is created, but it's not readable.

I am using Ubuntu 9.10 on a Fujitsu-Siemens T5010 tablet laptop.

Running it from the terminal I get:

GLib-ERROR **: /build/buildd/glib2.0-2.22.2/glib/gmem.c:175: failed to allocate 140737488355328 bytes

The crash happens at line 872 in xo-print.c:

g_string_append_len(pdfbuf, fontdata, len);

Examining the value of len with gdb prior to this call shows 140733193391464. But it's difficult to trace why, since len is optimised away earlier in the code. If I compile with '-g' or with '-O0' it works. So I guess I'll use '-O0' for now...

[khul (klas-physto)]

Compiling without optimisation was not the solution. It worked for annotating a test file, but the same error occured when saving an xournal file to pdf (without loading any pdf).

Now gdb worked fine, and I found that len is declared wrongly. It should be a guint32, not a gsize. Changing this declaration seemed to fix the bug.

Thanks for this report; it sounds like this an upstream bug. Would you mind posting a small explanation and patch to <email address hidden>?

Don't know if this helps, but I experienced exactly the described behavior today. I am running ubuntu 9.10 amd64 desktop variant on a macbook 3,1.
If possible, I could provide any helpful information. On the other hand, I understood this bug has been assigned to the xournal developers.

This bug is still present. Has anyone reported it to the xournal developers?

[Leandro (leandromartinez98)]

Just to mention, a very simple workaround of this problem is to "Print to file", with pdf output. It works.

[khul (klas-physto)]

I sent a mail to the sourceforge list Justin mentioned. It was held for moderation since I'm not a member, and I never received any comment. My fixed version (with gsize replaced with guint32) works just fine.

I have a fixed version in my PPA:

0.4.5-2 is in lucid

I'm not sure the fix works on my system (not available yet via Synaptic). What seems to happen is that when I open a XOJ file with text in it and then try to export as pdf, xournal dies abruptly and a zero KB output file is created. The problem does not occur when I export directly without first creating an XOJ file or if the XOJ file does not have text in it. Will have to try the save to pdf workaround--thanks!
