Error while starting kdevelop in Ubuntu 16.04

I am new in linux and i have installed ubuntu 16.04 64 bit on my machine. Installed kdevelop and while launching, I get the following error;

This application failed to start because it could not find or load the Qt platform plugin "xcb" in "".

Available platform plugins are: minimal, offscreen, vnc, xcb, eglfs, linuxfb, minimalegl, wayland-egl, wayland.

Reinstalling the application may fix this problem. Aborted (core dumped)

Tried debugging as mentioned in "Failed to load platform plugin "xcb" " while launching qt5 app on linux without qt installed

With QT_DEBUG_PLUGINS=1 /usr/bin/kdevelop, I get more details but i don't know how to resolve this :

Got keys from plugin meta data ("xcb")
Cannot load library /usr/lib/plugins/platforms/libqxcb.so: (/usr/lib/x86_64-linux-gnu/libQt5XcbQpa.so.5: symbol _ZTI20QEventDispatcherGlib, version Qt_5_PRIVATE_API not defined in file libQt5Core.so.5 with link time reference)
QLibraryPrivate::loadPlugin failed on "/usr/lib/plugins/platforms/libqxcb.so" : "Cannot load library /usr/lib/plugins/platforms/libqxcb.so: (/usr/lib/x86_64-linux-gnu/libQt5XcbQpa.so.5: symbol _ZTI20QEventDispatcherGlib, version Qt_5_PRIVATE_API not defined in file libQt5Core.so.5 with link time reference)"
This application failed to start because it could not find or load the Qt platform plugin "xcb"

Prior to this, I checked with ldd command and all the dependencies mentioned are available.

ldd /usr/lib/plugins/platforms/libqxcb.so
linux-vdso.so.1 =>  (0x00007ffe621d9000)
libQt5XcbQpa.so.5 => /usr/lib/x86_64-linux-gnu/libQt5XcbQpa.so.5 (0x00007fb60f5cc000)
libQt5DBus.so.5 => /usr/lib/x86_64-linux-gnu/libQt5DBus.so.5 (0x00007fb60f542000)
libfreetype.so.6 => /usr/lib/x86_64-linux-gnu/libfreetype.so.6 (0x00007fb60f224000)
libfontconfig.so.1 => /usr/lib/x86_64-linux-gnu/libfontconfig.so.1 (0x00007fb60efe1000)
libQt5Gui.so.5 => /usr/lib/x86_64-linux-gnu/libQt5Gui.so.5 (0x00007fb60ea57000)
libQt5Core.so.5 => /usr/lib/libQt5Core.so.5 (0x00007fb60e4e4000)
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007fb60e2c7000)

The list goes on. Any help would be really appreciated.

I encountered the same issue on Arch Linux. Running kdevelop from command line revealed the following error messages

kdevplatform.shell: Can't load plugin "kdevgdb" because a factory to load the plugin could not be obtained: "Cannot load library /usr/lib/qt/plugins/kdevplatform/31/kdevgdb.so: (libokteta2gui.so.2: cannot open shared object file: No such file or directory)" Connecting to deprecated signal

QDBusConnectionInterface::serviceOwnerChanged(QString,QString,QString) kdevplatform.shell: Can't load plugin "kdevokteta" because a factory to load the plugin could not be obtained: "Cannot load library /usr/lib/qt/plugins/kdevplatform/31/kdevokteta.so: (libkasten3okteta1controllers.so.1: cannot open shared object file: No such file or directory)"

It seems that kdevgdb depends on okteta which is not installed. I found a corresponding bug report

Installing okteta solved the issue.
