Included copy of Qt can't find installed plugins in /usr/lib32/qt4/plugins

[Ara Pulido]

Using Jaunty AMD64, libqt4core 4.5.0-0ubuntu3

Lib plugins are located under /usr/lib32/qt4/plugins/

But the lib is looking somewhere else:
hexdump -C /usr/lib32/libQtCore.so.4 | grep plugins
00197470 00 50 6c 75 67 69 6e 73 00 70 6c 75 67 69 6e 73 |.Plugins.plugins|
00197af0 2f 6c 69 62 2f 71 74 34 2f 70 6c 75 67 69 6e 73 |/lib/qt4/plugins|

There should be a symbolic link between /usr/lib32/qt4/plugins/ and /lib/qt4/plugins|

This is causing some Qt applications not finding the right imageformats.

Confirmed. This breaks the avatar functionality of Skype for example

[Matt Zimmerman (mdz)]

The plugins are in the correct place, and should be found by a normal library search. What does strace show?

[Martin Pitt (pitti)]

Ara, can you please do an strace of the affected application, to see what's going oin?

[Rick Spencer (rick-rickspencer3)]

Jonathan - as this is qt related, perhaps you would be best suited to comment on this?

[Rick Spencer (rick-rickspencer3)]

This bug is blocking the QA team from supporting a partner in the partner repository.

This is an issue with the copy of Qt as found in ia32-libs, there's no problem with the normal version of qt4-x11. Changing package appropriately.

Qt loads its plugins from /usr/lib/qt4/plugins/, someone familiar with the library tricks used in ia32-libs will need to work out if the 32-bit version can be persuaded to look in /usr/lib32/qt4/plugins/ instead.

for pango and gtk, runtime checks were required, checking the kernel personality at runtime.

[Ara Pulido (ara)]

Find attached the trace from strace.

[Robbie Williamson (robbiew)]

Attaching a POSSIBLE fix submitted by Bo, who requests testing by those affected.

[Scott Ritchie (scottritchie)]

Opening a qt4 task as the supplied patch by Bo needs to be applied in that package. After that a simple ia32-libs refresh can be done.

[Michael Terry (mterry)]

Just FYI, both qt4-x11 and ia32 libs in Karmic have this patch. So if we're still in the waiting-for-testing-to-confirm-patch-works stage, can Ara or someone else affected by this test with Karmic?

And then I'm guessing by the milestone that an SRU is desired?

[Scott Ritchie (scottritchie)]

What's the status in Lucid then? Can we close this?

[Matt Zimmerman (mdz)]

I don't see any reference to this bug number, or obvious reference to this problem, in the qt4-x11 or ia32-libs changelog in Lucid. mterry, can you clarify where and how this was fixed in Karmic?

[Jonathan Thomas (echidnaman)]

kubuntu_04_qt_ia32_library_path.patch should take care of this

[Jonathan Thomas (echidnaman)]

Assuming fixed in qt4-x11 due to the presence of the above-mentioned patch.

[Jonathan Thomas (echidnaman)]

Any reason for reopening this?
