scidavis crashed with SIGSEGV in QHeaderView::sectionSizeFromContents()

[der_vegi]

Binary package hint: scidavis

When I try to open this project (see attached file), Scidavis crashes with a Segmentation fault. Using Lucid Alpha 3, but this doesn't seem to be distribution specific, as it also happens in Karmic with the package from debian.physik.hu-berlin.de .

Confirmed in Ubuntu lucid alpha 3. Same version as reporter

Forwarded to https://sourceforge.net/tracker/?func=detail&aid=2965581&group_id=199120&atid=968214

I'll set an upstream link as soon as Launchpad lets me!

[Alex Valavanis (valavanisalex)]

Fixed upstream (still can't update this in Launchpad?!?) in r1282. Attaching patch from upstream revision

I attach debdiff with working patch.

Thanks!

[Fabrice Coutadeur (fabricesp)]

Hi,

Can you add a DEP3 header to the patch, and also thank Alex in the changelog entry? (he is the one that reported upstream, and found the patch).

Thanks,
Fabrice

[Angel Abad (angelabad)]

Thanks Frabrice for your review. Upload new debdiff with your suggestions.

[Fabrice Coutadeur (fabricesp)]

Hi,

One last thing: Alex is not the author of the patch; this is knut_f (http://scidavis.svn.sourceforge.net/viewvc/scidavis?view=rev&revision=1282), so please update the DEP3 header.
Also, you deleted part of the original patch (the second part). Can you fix the patch?

Thanks,
Fabrice

[Angel Abad (angelabad)]

Sorry Fabrice for the delay, I updated the patch author in header. I remove the las part of patch becouse the ubuntu version is different since patch creation. Now, only with the first patch scidavis works well.

Thanks!

[Angel Abad (angelabad)]

Sorry, I was wrong and resuscribed ubuntu universe sponsors, I cant remove it again. Sorry for the inconvenience.

Thanks!

This debdiff didn't solve the problem for me, still crashing if I try to create a new column in a table. It has changed slightly though, it used to hang for a second or two, and then crash, now it crashed instantly when I create the column.

[Fabrice Coutadeur (fabricesp)]

Hi,

This is another issue, not linked to this bug report. I've seen in Debian that there are issues with qt 4.6, fixed in 0.2.4. I'll try to get this updated. Uploading this fix in the meantime.

Thanks,
Fabrice

[Jonathan Musther (musther-deactivatedaccount)]

Sorry, thought it was the same issue. So it's a qt issue, thanks.

[Launchpad Janitor (janitor)]
