Description jaguarwan 2005-11-03 01:18:10 UTC

Version:           1.2 (using KDE 3.4.2, compiled sources)
Compiler:          gcc version 3.3.6
OS:                Linux (i686) release 2.6.14

Hello,

First of all, many thanks for writing Kiten, this is truly a great application to learn japanese with :)

I have accidentaly stumbled upon a little bug; Kiten gets shot down with a SIGSEGV when the main window is closed[1] and there is some "not yet validated" input[2] in the search field.

[1] Interestingly enough, I have found that this bug does not happen when Kiten is closed with File > Quit.

[2] I use kinput2 + canna to input kana/kanjis. By "not yet validated" input, I mean some kana freshly typed, with the grey highlighting: Return was not pressed, so no conversion/validation was done. Sort of "input still in the buffer" state ?

This really is a corner case, but since I was able to reproduce it reliably, I thought it may be worth reporting.

Here is the trace Kcrashhandler printed:

I use the Canna-3.7p3 and kinput2 3.1 binary packages from the Slackware Add-on Package project (http://sourceforge.jp/projects/sap/), and the Xorg 6.8.2 and KDE 3.4.2 from Slackware-current.

Thank you for reading this far, and have a nice day :)

Raphaël Prevost.
