IceWM restarts when right-clicking taskbar button of application that has dTitleBar: 0

[marcelkorpel]

Using version 1.4.2.712 in Arch Linux (using the AUR package), when I set dTitleBar to 0 within winoptions for a certain (set of) window(s), right-clicking the taskbar button of that application results in a restart of IceWM.

For instance, I added

Navigator.dTitleBar: 0

to my winoptions and started Firefox. The title bar isn't shown, as expected. However, clicking on the taskbar button restarts IceWM (noticable by watching htop) instead of the window menu popping up. This setting does not affect other window buttons on the taskbar, nor is it a problem with the Firefox window alone (I tested with several applications).

This is different from hiding the title bar of all maximized windows using HideTitleBarWhenMaximized=1 in preferences, as the behaviour is as expected in case of Firefox, but the same issue shows up when right-clicking urxvt taskbar buttons.

EDIT: The same happens when trying to open a menu of a toolbar button. E.g., my toolbar contains

menu Terminals xterm {
  prog alsamixer xterm urxvt -geometry 80x25 -e alsamixer
}

and when I click on the terminal icon, IceWM restarts.

It also results in all windows being drawn ±25 pixels lower.

Your commit solves the issue of IceWM restarting when right-clicking a taskbar button of a window without a title bar, but the second issue (described in the edit, probably unrelated) is still there.

BTW, do you know how to get a notification about commits mentioning an issue? I only coincidentally opened this issue again, seeing there's a commit that could solve it. Otherwise, can you please add a comment when committing something that might solve an issue, so I get notified? Thanks.

@marcelkorpel better not edit, but add a new comment. BTW try Watch or Github Help.

The 25 pixels lower is a useful feature to warn a crash happened, otherwise they go unnoticed.

Thanks a lot for reporting this. Should work now.

Okay, I'll submit a comment next time, to keep things clear.

The menu is now shown, too. Thanks!
