ygraph crashes when loading a file

[Tom Dörffel]

General information:

1) Operating system: Linux Mint 13 Maya, Release: 13
2) ygraph version:0.16~cvs20090218-1.1

Loading a file into ygraph with the command:

$ ygraph <file1>

allways leads to crashing the program with a segfault:

(ygraph:17237): Gdk-CRITICAL **: IA__gdk_text_height: assertion `font != NULL' failed

(ygraph:17237): Gdk-CRITICAL **: IA__gdk_text_width: assertion `font != NULL' failed
Speicherzugriffsfehler

Normally, the program should show an animated 2D plot of the input data.

Obviously there are two packages missing in the dependency list: xfonts-75dpi xfonts-100dpi
Installing them fixes the problem.

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

Does not work for me even with the fonts packages installed :(

$ ygraph testdata.xl

(ygraph:8628): Gdk-CRITICAL **: IA__gdk_text_height: assertion `font != NULL' failed

(ygraph:8628): Gdk-CRITICAL **: IA__gdk_text_width: assertion `font != NULL' failed
Segmentation fault (core dumped)

$ cat testdata.xl
1 0.5
2 0.765
3 1
4 0.8

What is wrong? :(

Sorry, but I can't help you.

I ran your test data and it worked.

You're really sure, you installed the correct packages?

The attached patch relaxes the font requirements.

I am on raring and have the same error.

Installing the font packages did not help.

same problem!

and now solved!

1) issue:
installed ygraph, and it crashed upon opening a file. (ygraph 0.16~cvs20090218-1.2ubuntu1)

2) suggested fixes in this thread:
i confirm that installing xfonts-75dpi and xfonts-100dpi DOES NOT resolve the problem. (at least, by themselves they are not sufficient.)

the patch provided above in this thread is also useless, without further instructions on how to use it.

3) solution:
installing the package libtiff-dev DOES resolve the problem in my case.

sudo apt-get install libtiff-dev

hope this helps someone...

The problem still persist for me unfortunately.
I tried everything listed in the above posts, but the error message still persists.
I can confirm that it is most likely tied to Mint, because I installed ygraph on Ubuntu on a separate machine and there, it works as expected!
