Package: mayavi2 Version: 2.1.1-2 Severity: important Hi!
As I commented on bug #478017, I don't see mayavi2 crashing at startup. On the other hand, I experience crashes after performing some operations. Please note that I've just upgraded mayavi2 from version 2.1.1-2 to version 2.1.1-2+b1, but I've seen the same issue on last Monday with version 2.1.1-2. I could reproduce this bug as follows. Let's take (again!) the test case I prepared for bug #400406 (see [1] and [2]). [1] http://bugs.debian.org/400406 [2] http://bugs.debian.org/cgi-bin/bugreport.cgi/vtk-multiblockPLOT3D-bug-test.tar.gz?bug=400406;msg=5;att=1 $ tar xvzf vtk-multiblockPLOT3D-bug-test.tar.gz $ ls gen_tinyplot3d.f tiny.q vtk-multiblockPLOT3D-bug-test.tar.gz list_plot3d.py tiny.xyz $ mayavi2 > ~/tmp/mayavi2.out 2> ~/tmp/mayavi2.err The main window shows up. * from menus, select File -> Load data -> PLOT3D file * as XYZ Co-ordinate file, select `tiny.xyz' * as Q Solution file, select `tiny.q' * select PLOT3D:tiny.xyz, tiny.q in the MayaVi pane * in the PLOT3DReader tab (inside the object editor), check "Binary file", "Do not reduce number of outputs", "Has byte count", and "Multi grid"; *un*check "Force read", "I blanking", and "Two dimensional geometry"; select "little_endian" Byte order * in the Reader tab, click on the "Update Reader" button OK, now we are ready to visualize the data... * from menus, select Visualize -> Modules -> Surface (a blue square shows up in the TVTK scene) * in the MayaVi pane, right-click on PLOT3D:tiny.xyz, tiny.q and choose copy from the context menu Boom! Segmentation fault! Relevant info in /var/log/kern.log: python[7379]: segfault at 2b7915ea1f40 rip 4b46cb rsp 7fffa3e3ccd0 error 7 File ~/tmp/mayavi2.out is empty: $ cat ~/tmp/mayavi2.out File ~/tmp/mayavi2.err includes just a (possibly irrelevant) message: $ cat ~/tmp/mayavi2.err (python:7379): Gtk-CRITICAL **: gtk_widget_set_colormap: assertion `!GTK_WIDGET_REALIZED (widget)' failed After this test, I said to myself: "OK, let's see if this bug is well reproducible". Hence, I started the above procedure over again. To my surprise, I repeated all the above steps and didn't get a segfault at the same point! When I chose copy from the context menu, the command was accepted. Then I added one more step: * in the MayaVi pane, right-click on TVTK Scene 1 in order to choose paste from the context menu Boom! Memory corruption! The following messages were spit out to the terminal (despite my stdout and stderr redirections...): *** glibc detected *** python: malloc(): memory corruption (fast): 0x00000000045 83360 *** =======
