New issue 1748 by [email protected]: ibus-ui-gtk3 crashed with SIGTRAP
right after changing keybinding in Kubuntu 14.10
https://code.google.com/p/ibus/issues/detail?id=1748
What version of the product are you using? On what operating system?
OS (Linux distributions, UNIX or ...):Kubuntu 14.10
Architecture (i386, x86_64):x86 32bit
IBus version:1.5.8
Input method name and version:chewing 1.4.10
Python version:2.7.8
dbus version:1.8.8
dbus-python version:1.2.0
gtk version (if bug is about gtk applications):3.12.2
qt version (if bug is about qt applications):4.8.6
## Reproduce steps
1. Launch ibus-setup
2. Change switch input method keybinding to <ctrl><shift><release>
3. Restart ibus
## Expected behavior
ibus running normally with the new keybinding setuped.
## Current behavior
ibus crashed right after restarting with
```
traps: ibus-ui-gtk3[4182] trap int3 ip:7fb5db001d30 sp:7fffb2526670 error:0
```
in kernel log
## Stacktrace
`````
(gdb) run

(ibus-ui-gtk3:6382): Gdk-ERROR **: The program 'ibus-ui-gtk3' received an X
Window System error.
This probably reflects a bug in the program.
The error was 'BadValue (integer parameter out of range for operation)'.
(Details: serial 647 error_code 2 request_code 131 (XInputExtension)
minor_code 54)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the GDK_SYNCHRONIZE environment
variable to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
Program received signal SIGTRAP, Trace/breakpoint trap.
