Scaling Crashes Docky

[Seif Sallam]

i realized that Docky doesn't crash because of the panel mode it actually crashes because of the scaling, when Docky uses all the screen wide; when it needs more space it scales down every icon on the dock so the dock can fit the screen.

Steps to make it crash:
1. Run Docky
2. Fill the Docky with icons till it touches the sides of the screen
3. Run more applications and close it (just force the Docky to scale up and down X times)
4. Congratulations

The Log in comment #3

System information:
Ubuntu 9.10 i386 && x64
Environment Gnome 2.28.1
Kernel: Linux 2.6.31-19-generic

------------OLD REPORT------------------
using Docky in panel mode crashes after some scaling, and this means that if i have a full icons on Docky and i opened another application it should scale down every icon so it fits the screen, but after 2 or 3 times of scaling up and down it crashes.

this problem i noticed happen more often on Ubuntu 9.10 i386 than on x64.

Crash traces or it didn't happen.

When reporting a bug (especially a crash), you need to include the following information:

1) Steps to reproduce (if possible, this is very important!)
2) A stack-trace / console log (if it crashes, the stack trace is dumped to the console)
3) System information such as OS/platform/anything else possibly relevant

Run Docky from a terminal with the '--debug' flag, recreate the crash and give us the output.

[Robert Dyer (psybers)]

I can not reproduce this, so you will have to get us a trace.

There is no crash in that log. Do you perhaps mean it is frozen?

The difference is that when it freezes you can still see it, but it won't respond to your mouse/keyboard at all and you must kill the program. A crash the program exits on it's own.

[Seif Sallam (seif.sallam)]

Yes, it Freeze. and thanks for the clarification.

[Robert Dyer (psybers)]

In that case, what you need to do is a tad bit different.

While Docky is still running (but frozen), you need to open a *new* terminal, find the PID for docky (ps aux|grep Docky.exe) and then run this:

$ kill -SIGQUIT <pid>

This will cause a dump to appear on the *original* terminal you started Docky from. *NOT* the new one you just opened.

Then give us the log from the original terminal again, which should include a trace this time.

Same freeze situation on my PC, I will attach a log as soon as it freezes again.

Besides, I love this dock!!
