Segfault on unchecking "Only Show Current Language" in fcitx-configtool

[Adnan Shameem]

I'm on Kubuntu 15.10 32 bit.

1)
$ lsb_release -rd
Description: Ubuntu 15.10
Release: 15.10

2)
$ apt-cache policy fcitx
fcitx:
  Installed: 1:4.2.9-3
  Candidate: 1:4.2.9-3
  Version table:
 *** 1:4.2.9-3 0
        500 http://mirror.dhakacom.com/ubuntu-archive/ wily/main i386 Packages
        100 /var/lib/dpkg/status

3) What you expected to happen
Not crashing and correctly populating the languages under "Available Input Method" list.

4) What happened instead
The dialog box Closed. Terminal output shows Segmentation fault. (Discussed below.)

Steps to reproduce:

1. Run fcitx
2. Open "Fcitx Configuration"
3. Uncheck "Only Show Current Language"
(in a few seconds the dialog box closes.)

In terminal I ran fcitx-configtool and then tried to Uncheck the checkbox. The dialog closed and the output is shown as follows:

$ fcitx-configtool
kcmshell5 with modules ' "org.kde.kcmshell_kcm_fcitx" ' is already running.
' "org.kde.kcmshell_kcm_fcitx" ' closed, quitting.

If I run it second time and try to uncheck, the output in terminal changes:

$ fcitx-configtool
QFont::setPointSize: Point size <= 0 (0), must be greater than 0
QFont::setPointSize: Point size <= 0 (0), must be greater than 0
QFont::setPointSize: Point size <= 0 (0), must be greater than 0
Segmentation fault (core dumped)

I am not expert on bug reporting. Hope the info helps.
