[Writer] Piechart problem

[fwn]

Hello,
I’m posting this question because I have a strange problem.
Since I’ve installed LibO 4.1.x I have to rebuild all the piecharts built with Calc and embedded into Writer with a simple table.
In other words, I can insert any number of percentages into the piechart, but when I save the file in PDF format and then I reopen the document every piechart has only one percentage and no other ones.
I have to modify every chart manually and save them again, but when I reopen the file next time there are only one percentage again.
With LibO 4.0.x there wasn’t this problem.
These are some examples of my problem.

1. this is how the piechart looks every time i open the document:

2. this is how the piechart should be:

Have I to submit a bug for this problem?

Problem solved.
I had to uninstall LibO 4.1.x and reinstall LibO 4.0.x.
I hope next version will fix the bug.
By the way, this is not the only problem with the graphs. The column graph is bugged too.
