Public bug reported:
Steps to reproduce:
- from a bluetooth device such as a mobile phone, send a few dozens (even
small) files via bluetooth to the computer
Observed: for every single file, one new popup appears informing you
that you have received one file, with the three options: open, reveal,
ok.
The result is that you end up with dozens of little windows like this, which
causes two problems:
1. you have to manually close each and every one of them clicking "ok". by the
way they are scattered all around
2. the system hangs with a process called "metacity" consuming 100% CPU.
After several minutes, metacity stops eating all cpu, so you are able to
operate the system, but every time you hit the OK button on one of the
popups to close it, metacity starts again eating up 100% cpu and the
system hangs again for some minutes before you can close the next popup.
The only way out is to kill the metacity process, but then every window
in the desktop looses its decorations (I guess metacity is the window
decorator, isn't it?)
Expected: only ONE popup should appear. If more files are received while the
popup is already open, its text should change to read "You have received N
files".
It seems to me there are 2 bugs here:
- a bug in the program that handles files received via bluetooth, which should
only open ONE popup. Note this is not a feature request, this is a bug, because
it is fundamentally wrong to open an unpredictably great number of windows that
have to be closed one by one manually triggered by a process that is not
started by the user. It's wrong and ridiculous and harmful.
- a bug in metacity that eats 100% cpu for several minutes just to create
"many" windows (less than 100, indeed it started hanging at 20 or 30). Even
more buggy is the fact that just closing ONE windows seems to hang it again (as
if closing a single windows required a time proportional to the total number of
existing windows)
