apport-gtk crashed with struct.error in read32(): unpack requires a bytes object of length 4

Status changed to 'Confirmed' because the bug affects multiple users.

happened to me whilst trying to report another crash. clicked on the details button.

same here updated 12.10 Xubuntu

Confirm with 12.10 ubuntu

Confirm. After updating system, apport tried to report another crash and then hit this bug.

Ubuntu 12.10

Ok, this might not be related, but today on my Lubuntu Quantal system, I was upgrading & updating. I had a problem with upgrading lxsession which required apt-get -f install to fix. Around the time I ran it, I got a crash report dialogue from Chromium, then apport ran and I ended up with this error.

Looking in /var/crash, for the given day, there is only one file, a 0-length _usr_bin_lxsession.1000.uploaded. Three days before (the last time I used the given system), there's also a 0-length _usr_bin_lxsession.1000.upload. That same day, there is a _usr_bin_lxsession.1000.crash, which seems to have the most relevant comment of `SegvAnalysis: Skipped: missing required field "Disassembly"` It also complains lxsession is not up to date.

So I don't know how this might relate except for that error, and sadly, outside of the .crash (which is not apport-gtk and is thus not relevant), I don't have any other data to provide. However, since I wasn't successful in creating a bug report and I'm not totally sure of what led to what happening, I'm not about to file a "just riding along" sort of bug report. So I hope that this information is in some way helpful here. If you need further information, please let me know.

Happened just after I rebooted post an update in 12.10

After upgrade the system (12.10)

v 12.04 and 12.10 are so buggy :-(

try this guys
root@<user>:~# apt-get upgrade apport-gtk

The original traceback says:

It has the same flow as in

https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1064357

and differes only in some line xxx ; not from content, only from number.

Because bug 1064357 has already got a priority as "High" by "jibel" I close this here as dublicate of jibels report, even when this here is older.

When you have .crash files in your folder

/var/crash

that reproduce the problem for sure ,please attach them on bug 1064357

Thank you
