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

[Scott Howard]

** Description changed:

  Binary package hint: qtiplot
  
  With Ubuntu 9.04, my qtiplot worked fine.
  
  After updating to 9.10, qtiplot quits without any message or error every
  time I want to plot or fit any data. I used the same data and the same
  sheeds I also used before the update.
  
  I am using the version 0.9.7-1 of qtiplot, installed via synaptic. I
  also tried to reinstall the program, which didn't change anything.
+ 
+ ________
+ 
+ 
+ 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.
