Program crashes when doing any plot or fit

Thank you for your bug report and working to make Ubuntu better!

Try qtiplot from this ppa:
https://launchpad.net/~showard314/+archive/ppa

(instructions are on that link on how to add it to your sources list) Let me know how it works.

I'm sorry for the extra emails, as I find out more and more about this
bug I'm posting in case some one else takes over.

On Oct 13 there was a rebuild that failed on all architectures:

I think it is related to this bug since Karmic has a version that
built on older versions of libraries that were subsequently updated,
but qtiplot was not updated since before Jaunty.

I reproduced the bug, made the patch, rebuilt, and confirmed the bug no longer exists with the patch.
Here is the formal SRU request:

1) This program is will not work for anyone in karmic. It will load, but when you try to plot anything, it will crash. This is due to this package being uploaded during the Jaunty development cycle and relying on library version we had in Hardy. Specifically, the qwt and Sip libraries cause a FTBFS and segfaults the program when run (see comment #2 above).

2) This has been addressed in the development branch by releasing new versions that depend on newer libraries. However, no one merged or synced this in over a year. Rather than try to do an SRU of a total version update, we can try to just fix this bug and teach it to use the current shared libraries.

3) Attached is the minimal patch (debdiff).

4) Test case:
1) load qtiplot
2) put dummy values in the X and Y columns (e.g. 1 and 2 in the X column; 4 and 5 in the Y column)
3) select the Y column, then chose "Plot" and "Line"
4) BOOM! (see screen shot for what it is supposed to look like, using the patched version)

5) Regression potential: none. It is totally unusable now, it can't get any worse.

debdiff patch

Proposed merge and diff:

what it's supposed to look like when it is working

build log on AMD64 -- SRU, do you want a ppa of this too? I can't upload to karmic-proposed, should we get a motu sponsor?

This is a regression, marking as Critical as per:
https://wiki.ubuntu.com/StableReleaseUpdates

as per jdong's help on IRC, this now targets karmic-proposed

ACK from MOTU-SRU.

I installed QtiPlot from your PPA, and it works fine now and does all the fitting and plotting as usual.

Thank you very much for the quick help, it's great that this program works again on my system!

Accepted qtiplot into karmic-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

the new version in -proposed works fine here!

Works for me as well.

Everything works perfect again with the proposed version.

Thanks again for the immidiate help.

Thanks for fixing this bug. I found out about this bug 2 days ago and it's already fixed now. This is quick!
