Shotwell crashes if disk with images is not mounted

Sam,

I can't reproduce this. I'm also on Ubuntu 10.10 with Shotwell 0.7.2-0ubuntu2. I created a new library and imported some photos from an external hard drive connected via USB. When I disconnect the hard drive and start Shotwell, there is no crash and all photos appear in the Missing View as expected.

What kind of external disk are you using?

If you can reproduce this crash, it would help us if you could generate a stack trace. To do that, first install the Ubuntu packages libc6-dbg, libglib2.0-0-dbg and libgtk2.0-0-dbg (these contain debug symbols). Then from the command line run 'gdb shotwell' to run Shotwell in the debugger. Once Shotwell crashes, type 'where' in gdb; that will show you a stack trace which you can copy and paste into a comment here. Thanks!

Hi,
The debug symbols dont seem to work.. I get the following:

How do I get them into the right place.

Thanks,

Hi Sam,

Our PPA has a binary version of Shotwell with debug symbols. You can find it here:

https://launchpad.net/~yorba/+archive/ppa

To get Shotwell from it, go into Synaptic and add this in Settings -> Repositories -> Other Software:

deb http://ppa.launchpad.net/yorba/ppa/ubuntu maverick main

You'll need to re-install Shotwell after doing this.

Thanks,

-- Jim

Hi,

I have followed the instructions and got the following stack trace, I hope it helps!

Thanks,

Sam

Hi Sam,

Yes, this is good, but the stack trace is incomplete. (I should have clarified Adam's instructions when I posted about the PPA. My fault.) If you would be so kind to reproduce it again, but doing it this way so I can get a complete backtrace:

At the command prompt, run Shotwell like this:

    $ SHOTWELL_LOG=1 gdb shotwell 2>&1 tee shotwell.gdb

At the gdb prompt type "run":

    (gdb) run

Then reproduce the problem. After Shotwell crashes type this at the gdb prompt:

    (gdb) backtrace full

and exit gdb. If you could attach the shotwell.gdb file and ~/.cache/shotwell/shotwell.log file to this ticket, that would be a huge help.

From this I get the following:

Not sure if this is 100% correct as it states that it is ignoring excess command line arguments. Also I dont seem to have permission to access .cache. I am fairly new to Linux so am probably...

Sam,

there was a typo in the command line Jim suggested. It should be

$ SHOTWELL_LOG=1 gdb shotwell 2>&1 | tee shotwell.gdb

Could you try again, and then attach shotwell.gdb and ~/.cache/shotwell/shotwell.log to this ticket?

Hi,

Unfortunately my Hard Disk died on Sunday and I have had to re-build my PC. I can unfortunately no longer produce the error.

Thanks for all the help.

Sam

I don't think we can keep this open without more information or a reproducible case here. I'm setting this to closed unless someone else can reproduce it.

> Unfortunately my Hard Disk died on Sunday and I have had to re-build my PC

closing this bug but feel free to report any other bugs you may find.

Another user has reported to us what appears to be the same problem: http://trac.yorba.org/ticket/2881. Investigating.

per upstream comment

This bug is old and not reproducible, so I'm closing it. If this still affects anyone with a current Shotwell build, feel free to reopen.
