gedit crashes when opening wget.info

[Michael Terry]

Binary package hint: gedit

Opening a seemingly normal file makes gedit think it's a weird encoding, interpret the file all weird, and eventually crash.

The file is wget.info from the wget package (attached). Opening it in less looks like ascii with some occasional odd characters. gedit briefly shows it as a bunch of asian characters (chinese?). Then it crashes:

*** glibc detected *** gedit: free(): invalid next size (fast): 0x09d31df0 ***

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please try to obtain a valgrind log following the instructions at https://wiki.ubuntu.com/Valgrind and attach the file to the bug report. This will greatly help us in tracking down your problem.

[Michal Parusinski (astenorh)]

It looks like the error might come from deeper than gedit.

I notice that on a x86 machine it caused a segmenation fault, but on a x64 machine it caused many strange characters.

[Tiago Silva (tiagosilva)]

When you say that "gedit think it's a weird encoding" that is correct to assume.
From what I recall wget.info isn't a regular file; It's a GNU Info binary document originally formatted from a texinfo typeset text.
It should be read/interacted with info because it contains special formatting and hyper-links.

As of the latest releases [citation needed] gedit will not crash, but will "gracefully" refuse to open this or any other binary files [0].

[user (meta1729-deactivatedaccount)]

Agree with Tiago Silva. The MIME type of wget.info is 'Application/Octet Stream'.

[Denis LE FUR (dlefur)]

Hello,
I have the same error.
This also happens with log files from LaTeX compilation including accents (I guess).

[Vadim Rutkovsky (roignac)]

Can't reproduce in gedit 3.3.3-0ubuntu1 - see comment #5

I suppose we can close this with Fix Released?

Yup. In precise's gedit, it warns me about the odd characters, and even if I choose to continue editing, does not crash.
