Segmentation fault on start

[isecore]

Binary package hint: liferea

Trying to start Liferea yields a segmentation fault. No signal 11 or anything like that. When run in a terminal it tries to start and then ends with the following:

(liferea:13349): GdkPixbuf-CRITICAL **: gdk_pixbuf_get_n_channels: assertion `GDK_IS_PIXBUF (pixbuf)' failed
Segmentation fault

Tried running it with --debug-all and it spits out tons of messages until it finally segfaults the exact same way.

Here's a backtrace.

My Backtrace attached.

and here somthign for the search engines,
The output just before the crash:

(liferea:23490): GdkPixbuf-CRITICAL **: gdk_pixbuf_get_n_channels: assertion `GDK_IS_PIXBUF (pixbuf)' failed

Program received signal SIGSEGV, Segmentation fault.
0x01a70290 in gdk_cairo_set_source_pixbuf () from /usr/lib/libgdk-x11-2.0.so.0
(gdb) backtrace full
#0 0x01a70290 in gdk_cairo_set_source_pixbuf () from /usr/lib/libgdk-x11-2.0.so.0

So could be caused by some incompatible GTK updates?

This is made on natty.

I managed to get it sorted, although I'm very fuzzy about what I did. I also got that GDK_IS_PIXBUF error as the final message before the segfault.

In my case, I noticed that it ran fine as root (sudo liferea) and after that I discovered that it ran fine if I created a fresh user and logged in there. So I went through all the files in ~ and deleted everything that looked old or irrelevant. Somewhere along this it got fixed. I have NO IDEA what I changed but it works again.

For me it started crashing after upgrading package "faenza-extras" from 0.9 to 0.9-ubuntu1 on 2011/06/22. Running Ubuntu Lucid. Removing the (now empty) package faenza-extras solved it for me.

[isecore (isecore)]

Yeah, you know what, now that I retrace my steps and think about it a little clearer - I did have that package installed, and I removed it as well. Seems we had the same problem and solved it the same way. Good to know!

[Jean-Peer Lorenz (peer.loz)]

The package didn't removed some links it had created on installation. And apparently this leads liferea to segfault. So, this bug are actually two:

1. Liferea shouldn't segfault (silently) just because some icons are not available.
2. faenza-extras is broken/contains packaging errors.

Somebody out there who wants to file bugs in their appropriate places?
