Bug#891954: ibus-libpinyin can't select character candidate except the first one.

[Ola Rende]

I feel this is a bug deserving more than "severity: normal", given that it 
almost completely destroys the OS's ability to input chinese characters. The 
fact that the workaround also destroys the cache of input training data is not 
great either.

Furthermore, the fact that the only mention of the workaround is in this thread 
and an AskUbuntu page, laypeople are going to need quite a bit of luck to find 
this.

Hi Sirong,

Thank you for your help.

I followed your instruction and deleted the ~./cache/ibus/libpinyin
folder. The problem solved.

I think we this bug report can be closed.

Thank you very much again.

Sincerely,
Bo Lan

Hi Bo Lan,

I got the same problem after recovering from a filesystem error.

The error can be reproduced exactly as you described.

I ran libpinyin in the terminal and got the following error message:

debian-user:~$ /usr/lib/ibus/ibus-engine-libpinyin --ibus
ibus-engine-libpinyin: ../src/lookup/phonetic_lookup.h:901: bool
pinyin::PhoneticLookup::train_result3(const
pinyin::PhoneticKeyMatrix*, const pinyin::ForwardPhoneticConstraints*,
MatchResult) [with int nbest = 3; MatchResult = _GArray*; GArray =
_GArray]: Assertion `m_user_bigram->store(last_token, user)' failed.
Aborted

So this error is related to the user data. When you select a phrase other
than the first one, libpinyin will try to store it in your home folder. If
it doesn't work it will fail and exit.

You may want to check the contents in ~/.cache/ibus/libpinyin/ . I simply
deleted all files in this folder and kill ibus-engine-libpinyin process to
restart it. They things come back to normal again. I think the problem you
have is likely to be the same as mine. If not please provide error messages
when you run ibus-engine-libpinyin in terminal

Thanks!

Package: ibus-libpinyin
Version: 1.9.2-2
Severity: normal

Dear Maintainer,

The ibus-libpinyin (Intelligent Pinyin) is not be able to select character
candidate other than the first one.

Once I input a pinyin for a Chinese character, by default, there are 5
candidates can be selected. If I need the first candidate, I can press 1 or
space on the keyboard to select it. It works. If I need one of the 2nd to 5th
candidates, however, I need to press 2 to 5 to select, and it doesn't work.

One pinyin can have many of characters, if we can select only one, the program
is not usable.
