[Bug 471238] Re: Program crashes when doing any plot or fit

[Scott Howard]

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.
