Comment 2 for bug 215574

Locale: Latvian, keyboard layout: Latvian (aposthrope)(by Tilde ltd.) Keyboard layout has one dead key "'".

Some more data: when locale is Japanese and keyboard layout is Latvian (similar to previous), it is completely impossible to input any modified characters, inkscape completely refuses to input "'"key (pressing "'" and "a" in sequece produces just "a"; presing "'"key once or multiple times, does not inputs anything)
These data are on version 0.46 win32 and system locale is Japanese, and Keyboard layout is Latvian (by Laacz (http://laacz.lv/f/misc/apos/apostrofs_punkts_vista32.zip)(can be downloaded here))

Changing locale to Latvian, exactly replicates in first description described problem (this bug appears to be independent on exact type of dead key keyboard layout).

Also, when using Japanese locale and Japanese keyboard layout, bug [https://bugs.launchpad.net/inkscape/+bug/166632] is still present (IME input box is located near corner of program window, not at the text input site)(however Japanes text input works properly)(except of this visual issue).
