I've found that saving to *.PNG a plot obtained in rxbag (for a given topic) fails. It just doesn't save anything.

Have someone found this same problem?

I'm using diamondback on Ubuntu 10.10, by the way.

UPDATE Still fails in electric with Ubuntu oneiric.

It works for electric on lucid in the one test case I tried (so at least it's not something generic).

It doesn't in my electric on oneiric, I have a seg fault. Could it be because I'm using my on msg type? Maybe, I forgot some serialization stuff. But, as far as I know, saving a png image is completely independent. Indeed, the plot is drawn, the problem is when I try to save it.

Do you do custom serialization? But it should be independent, when there is a plot. -- Does it just not work or does rxbag segfault, which it shouldn't. Maybe it's just some write permissions problem?

I use the python generated code for the msg I defined, so I don't write a single C++ line of code. So, no custom serialization, I realized after I wrote the comment. Last time I check it segfault, but usually it doesn't (I cannot check it again now). No permission problem, I select desktop folder.
